You would use inverse operations. I had this on my math homework and got it correct

so I know this!

Good for you ! You know what you said, but you don't know what you know.

I'd say that you use the Golden Law: "You must always do exactly the same thing

to both sides of an equation."

What is an equation with one or two variables?

When you solve a one-variable equation, your goal is to isolate the variable.To isolate the variable means to make it be alone on one side of the equals sign.In the equation shown here, you can isolate the variable by subtracting 9 from both sides of the equation and simplifying


To use inverse operations on both sides of an equation until the variable appears by itself on one side?

Isolate the variable


Why do you isolate the variable on one side the the equation when solving a linear equation?

Isolating a single variable in terms of the rest of the equation provides a solution to that variable. That is, if you know the equation that equals the variable, then you can figure out its value.


What is to isolate a variable on one side of an equation?

segregation or apartheid


How do you get a variable by its self?

To isolate a variable, you need to perform inverse operations to the ones applied to the variable. This involves moving constants to the other side of the equation, and then using operations like addition, subtraction, multiplication, or division to isolate the variable on one side of the equation.


For systems in which there is no linear equation you can isolate and substitute a variable that is what in both equations?

squared


Which operations would isolate the variable in this equation 3y - 12 14?

Division


Why do you isolate variables for math?

You isolate variables in math because the point of an equation is to solve for the variables. By isolating the variables you have learned what that variable stands for and thus solved the equation.


Why do you use an inverse operation?

Inverse operations are used to undo mathematical operations and isolate a variable. They help to solve equations and simplify expressions by moving operations to the opposite side of the equation. This allows us to find the value of the variable that makes the equation true.


Which operation would isolate the variable in this equation 51q equals 1020?

divide by 51


How do you solve for the value of a variable?

you isolate the variable to the left side of the equation and keep all other terms and factors to the right side, as in solving for x in 2- x = 2. You have to use basic algebraic manipulation to isolate the chosen variable, i.e., adding multiplying or dividing by an equal amount to each side of the statement in order to isolate x.


What is the definition of isolate the variable?

In algebra, its to move the pieces of the equation around so that the variable is isolated to only one side of the sign
