Front

What is the goal when solving equations with variables on both sides?

Back

The goal is to isolate the variable on one side of the equation to find its value.

Front

What is the first step in solving the equation 5x - 14 = 8x + 4?

Back

The first step is to get all terms involving the variable on one side and constant terms on the other side.

Front

How do you isolate the variable in the equation -5k + 10 = -2k - 14?

Back

You can isolate the variable by adding 5k to both sides and then subtracting 10 from both sides.
