1. r = 0
2. x = 0
3. v = -1
4. a = 1
Step-by-step explanation:
1. -18 + 36r = -18 + 4r
-18 + 32r = -18
32r = 0
r = 0
2. -8x - 14 = -14 - 28x + 4x
-8x - 14 = -14 - 24x
16x -14 = -14
16x = 0
x = 0
3. 5 -8v - 5 = -4 - 12v
-8v = -4 - 12v
4v = -4
v = -1
4. 3a - 18 = -5a - 7 - 3a
3a - 18 = -8a - 7
11a = 11
a = 1
