How do you isolate a variable in a two-step equation?

Back

To isolate a variable, perform the inverse operations in the reverse order: first eliminate any addition or subtraction, then eliminate any multiplication or division.

Solve for w: -6w + 1 = -11

Back

w = 2

Front

What does 'combining like terms' mean?

Back

Combining like terms means to simplify an expression by adding or subtracting terms that have the same variable raised to the same power.
