Answer
Fill the blank with: distribute $3(x-2)$ into $3x-6$ (distributive property)
Work Step by Step
When solving a linear equation, we want to isolate the unknown (x) on one side. If it is entangled inside parentheses or part of a fraction, we perform actions to get x out of them.
Here, x is inside a set of parentheses. To "set it free" we distribute the 3 over the parentheses; so instead of $3(x-2)$ we write $3x-6$ and continue simplifying.
