Answer:
x = 19
Step-by-step explanation:
1. add 31 on both sides (you wanna get the "x" by itself)
ex: 2x - 31 = 7
+31 +31
2. the 31s cancel each other out so now you add 31 + 7
2x = 7
+31
___________
38
3. divide 2 on both sides so the 2s cancel each other out and only the x is left
ex: 2x / 2 = x 38 ( the 38 stands alone)
4. now divide 38/2 and you have your answer
X= 19
The answer is (4x20) + (4x4) which equals 96
