An equation is shown below:

9(3x – 16) + 15 = 6x – 24

part a: write the steps you will use to solve the equation, and explain each step. (6 points)

part b: what value of x makes the equation true? (4 points)

Part A
9(3x – 16) + 15 = 6x – 24 
step 1: 27x - 144 + 15 = 6x - 24...expand by using distributive property
step 2: 27x - 129 = 6x - 24...simplify
step 3: 21x - 129 = -24 subtract 6x to both sides then simplify
step 4: 21x = 105add 129 to both sides then simplify
step 5: x = 5divvied  both sides by 21 then simplify

part B.
x = 5 makes equation true 

9[3(5) – 16] + 15 = 6(5) – 24
9(15-16) + 15 = 30 -24
9(-1) + 15 = 6
-9 + 15 = 6
 6 = 6 true
