Front

What does it mean to 'solve for x'?

Back

To 'solve for x' means to find the value of the variable x that makes an equation true.

Front

What is the first step in solving the equation x - 2 = 2x + 1?

Back

The first step is to isolate the variable x by moving all terms involving x to one side of the equation.

Front

In the equation x + 5 = 4x + 2, how do you start solving for x?

Back

You can start by subtracting x from both sides to get all x terms on one side.
