Write and solve an equation to find the value of the variable 104 137 154 x mean 130?
An equation to find the value of the variable 104, 137, 154 and x with a mean of 130 is: (104 + 137 + 154 + x)/4 = 130 395 + x = 130 * 4 x = 145.

Write and solve an equation to find the value of the variable. 5.2 8.3 8.5 7.7 7.8 y mean 7.1?
mean(5.2 + 8.3 + 8.5 + 7.7 + 7.8 + y) = 7.1=> y = 5.1
How do you solve a simultaneous equation with 3 variables?
You cannot have a simultaneous equation: you must have 2 or more equations for there to be any simultaneity.The simplest method to solve them is to invert the matrix of coefficients but this requires you to know matrix algebra and the question suggests tha you are not that advanced.In that case, express any one of the variables in terms of the other two. Substitute the resulting expression in the other equation(s). Repeat until you have only one variable. Find its value and substitute in the previous equation. That will then enable you to find a second variable. And so on.
Can you solve a system of equations you can replace a variable with an equal value or expression true or false?
True
The process of finding the value of the variable that makes it a true equation is called?
solve
How do you check to see if the value of the variable is a solution to the equation?
Substitute that value in the equation, and then check to see if the resulting statement is TRUE.
How doI solve system of equations by substitution?
Assuming the simplest case of two equations in two variable: solve one of the equations for one of the variables. Substitute the value found for the variable in all places in which the variable appears in the second equation. Solve the resulting equation. This will give you the value of one of the variables. Finally, replace this value in one of the original equations, and solve, to find the other variable.
How do you solve system of eqaution by subsitution?
To solve a system of equations by substitution, first solve one of the equations for one variable in terms of the other. Then, substitute this expression into the other equation. This will give you an equation with only one variable, which you can solve. Finally, substitute back to find the value of the other variable.
What is any value of the variable that makes the equation statement true?
A value of the variable that makes the equation statement true is called a solution. For example, in the equation ( x + 2 = 5 ), the value ( x = 3 ) is a solution because substituting it into the equation yields a true statement. There can be multiple solutions or none, depending on the equation. To find a solution, you can isolate the variable and solve for its value.
How do you solve a equation using unknown variables?
You don't use unknown variables to solve an equation. The purpose of solving an equation is to find the value of the variable so that it's no longer unknown.
What are the steps to solve a whole number equaiton?
To solve a whole number equation, follow these steps: Simplify both sides of the equation by combining like terms. Use inverse operations to isolate the variable on one side of the equation. Perform the necessary operations to solve for the variable. Check your solution by substituting the value back into the original equation to ensure it satisfies the equation.
How do you solve the equation 720 equals 2a x 3b x 5c?
I have the feeling that you were looking to find a value for each variable in this equation. Unfortunately you can only solve for each variable in terms of the other variables in this equation.
What should be added to both sides of this equation to solve for the variable a plus 39 equals -60?
-21
How do I plug in a variable?
You cannot plug in a variable, what you do is plug in the value for a variable. If you know the value of the variable in an equation (or formula), the process of replacing that variable whenever it appears in the equation by its value is called plugging in the value for the variable.
What does value of variables mean?
In algebra, variables are represented by letters such as x. A variable could be any number. That number is the "value" of the variable. In an expression, you can choose a number to put in for x, and simplify to get a number which is the value of the expression. In an equation, you can solve for the value of x, which will be the value of x which makes the equation true.
Two step equation definition?
A two-step equation is a mathematical equation that requires two steps to solve. It involves applying inverse operations to isolate the variable on one side of the equation. The goal is to determine the value of the variable that satisfies the equation.
