Front

What is the first step to solve the equation 5x + 4 = 64?

Back

Subtract 4 from both sides to isolate the term with x.

Front

What is the second step to solve the equation 6w - 1 = 11?

Back

Add 1 to both sides to isolate the term with w.

Front

What does it mean to isolate a variable in an equation?

Back

Isolating a variable means to manipulate the equation so that the variable is on one side and all other terms are on the opposite side.
