How to solve equations with variable on each side?
BellahrachHajargp215...
There are different techniques, depending on the specific situation. In the simplest case, you transfer all the variables to one side. Here is an example:
4x = 2x + 16
Subtract "2x" on each side:
2x = 16
Now you have a single variable, on only one side.

How do you solve algebra equations?
-- You select an operation. -- You apply the same operation to each side of the equation. -- You keep doing both steps until the equation says (the variable) = (the value of the variable)
How do you use different techniques to solve linear equations?
There are several techniques to solve linear equations. One common technique is the elimination method, where you eliminate one variable by adding or subtracting equations. Another technique is substitution, where you solve one equation for a variable and substitute it into the other equation. You can also use matrices and row operations to solve linear equations.
What does it mean for a coordinate pair to be a solution to a system of equations?
It means that if you replace one variable with one of the numbers, and the other variable with the other numbers, and then evaluate the expressions on each side of the equations, the equalities will be true.
What is the basic rules to solve equations?
The basic rules to solve equations are to isolate the variable on one side of the equation by performing the same operation on both sides. This includes adding or subtracting the same value, multiplying or dividing by the same value, and applying exponent or logarithm rules if necessary. The goal is to simplify the equation until the variable is alone on one side and the solution can be determined.

How do you solve equations that contain multiple opeations?
You undo one of the operations at a time, always with the aim of isolating the variable you want to solve for on one side.
What is usually the first step in solving a system of nonlinear equations by substitution?
The first step is usually to solve one of the equations for one of the variables.Once you have done this, you can replace the right side of this equation for the variable, in one of the other equations.

Find the value of y when 7y plus 11 equals 3y plus 25?
Solve the equations by moving the variable to one side : 7y + 11 = 3y + 25 (subtract 3y from each side) 4y + 11 = 25 (subtract 11 from each side) 4y = 14 Y = 3.5

How do you solve an equation with a variable on each side?
It's not always to 'solve' as it is to 'simplify' EX: 15a + 3b = 45c simplifies to 5a + b = 15c
Which is the best way to solve the equation?
That depends on the equation. In general, you'll try to isolate the variable, by using operations (on both sides of the equation) that get rid of anything other than the variable, on the side the variable is on.
What do you do when you have a negative variable?
When you have a negative variable in an equation that you are trying to solve for, you multiply each side of the equation by -1. If it is an inequality such as <, you would flip the sign to > and vice versa.
How do you solve this equations 4x plus 5 equals 13?
4x + 5 = 13. To solve algebraic equations, you need to get the variable by itself on one side of the equation. Start by subtracting 5 from both sides >>> 4x = 8. Then divide both sides by 4 to find what 'x' equals >>> x = 2.
