How do you solve y equals x-3 and 2x equals y equals 3?
The second "equation" is, in fact, two equations, and the three equations are inconsistent.The "second" equation gives :2x = 3 so that x = 3/2 and also y = 3But substituting these values in the first equation implies that 3 = (3/2) - 3or 3 = 3/2 or 2 = 1 which is a contradiction.The second "equation" is, in fact, two equations, and the three equations are inconsistent.The "second" equation gives :2x = 3 so that x = 3/2 and also y = 3But substituting these values in the first equation implies that 3 = (3/2) - 3or 3 = 3/2 or 2 = 1 which is a contradiction.The second "equation" is, in fact, two equations, and the three equations are inconsistent.The "second" equation gives :2x = 3 so that x = 3/2 and also y = 3But substituting these values in the first equation implies that 3 = (3/2) - 3or 3 = 3/2 or 2 = 1 which is a contradiction.The second "equation" is, in fact, two equations, and the three equations are inconsistent.The "second" equation gives :2x = 3 so that x = 3/2 and also y = 3But substituting these values in the first equation implies that 3 = (3/2) - 3or 3 = 3/2 or 2 = 1 which is a contradiction.
How can you solve problems involving equations that contain addition subtraction multiplication or division?
To solve problems involving equations with addition, subtraction, multiplication, or division, start by isolating the variable on one side of the equation. Use inverse operations to eliminate terms, such as adding or subtracting to remove constants and multiplying or dividing to eliminate coefficients. Simplify the equation step-by-step, ensuring to perform the same operation on both sides. Finally, check your solution by substituting the variable back into the original equation to verify its accuracy.
How do you work a simultaneous equation?
You cannot work a simultaneous equation. You require a system of equations. How you solve them depends on their nature: two or more linear equations are relatively easy to solve by eliminating variables - one at a time and then substituting these values in the earlier equations. For systems of equations containing non-linear equations it is simpler to substitute for variable expression for one of the variables at the start and working towards the other variable(s).
What is general equation?
A general equation typically refers to a mathematical expression that represents a relationship between variables. It can take various forms depending on the context, such as linear equations, quadratic equations, or differential equations. The general equation aims to encapsulate a wide range of specific cases or instances within its framework, often allowing for the derivation of particular solutions by substituting specific values for the variables.

What do you do when you have two equations mutiply or divide?
To solve two simultaneous equations - usually two equations with the same two variables each - you can use a variety of techniques. Sometimes you can multiply one of the two equations by a constant, then add the two equations together, to get a resulting equation that has only one variable. Sometimes you can solve one of the equations for one variable, and replace this variable in the other equation. Once again, this should give you one equation with a single variable to be useful.
Do Radical equations sometimes have extraneous solutions?
Yes, radical equations can sometimes have extraneous solutions. When solving these equations, squaring both sides to eliminate the radical can introduce solutions that do not satisfy the original equation. Therefore, it is essential to check all potential solutions in the original equation to verify their validity.
What do you call to an equation that contains radical with variable in the radicand?
An equation that contains a radical with a variable in the radicand is called a radical equation. These equations typically involve square roots, cube roots, or higher roots, and the variable is located inside the radical symbol. Solving radical equations often requires isolating the radical and then raising both sides of the equation to an appropriate power to eliminate the radical.
Who Invented the Substitution Method?
The substitution method in mathematics is a technique used to solve systems of equations by isolating one variable and substituting it into the other equation. The method is not attributed to a single inventor, as it has been used by mathematicians for centuries. The concept of substitution in algebra can be traced back to ancient civilizations such as the Babylonians and Greeks, who used similar methods to solve mathematical problems.
How you know that the value of d is the same in both equations?
To determine that the value of ( d ) is the same in both equations, you can isolate ( d ) in each equation and compare the resulting expressions. If both equations yield the same expression for ( d ) when simplified, then the value is confirmed to be the same. Additionally, substituting known values from either equation should yield consistent results for ( d ).
Can solve a system of linear equation by substitution?
Yes, a system of linear equations can be solved by substitution. This method involves solving one of the equations for one variable and then substituting that expression into the other equation. This process reduces the system to a single equation with one variable, which can then be solved. Once the value of one variable is found, it can be substituted back to find the other variable.
