Consider the sequence of steps to solve the equation: 2 (x - 4) + 6x = 9x - 10
Which step in solving this equation is justified by the Commutative Property of Addition?
Given ⇒ 2 (x - 4) + 6x = 9x - 10
Step 1 ⇒ 2x - 8 + 6x = 9x - 10
Step 2 ⇒ 2x + 6x - 8 = 9x - 10
Step 3 ⇒ 8x - 8 = 9x - 10
Step 4 ⇒ 8x - 8x - 8 = 9x - 8x - 10
Step 5 ⇒ 0 - 8 = x - 10
Step 6 ⇒ - 8 = x - 10
Step 7 ⇒ - 8 + 10 = x - 10 + 10
Step 8 ⇒ 2 = x + 0
Step 9 ⇒ 2 = x
+2
