3. Justify each step of the solution by stating the property that was used to get to each step.
Given: 2(10 − 13x ) + 9x = −34x + 60
Step 1: 20 − 26x + 9x = −34x + 60
Step 2:
−17x = −34x + 40
Step 3: 17x = 40

Step 4:


x = 40 17

2(10 - 13x) + 9x = -34x + 6020 - 26x + 9x = -34x + distributive property-17x = -34x + subtraction property (subtracted 20 from both sides)17x = addition property (added 34x to both sides)x = 40/ division property (divided both sides by 17)
