i) 36 + v = 15
Subtract 36 from both sides:
36 + v - 36 = 15 - 36
36 - 36 + v = 15 - 36
v = -21
ii) h - 94 = -68
Add 94 to both sides:
h - 94 + 94 = -68 + 94
h = 26
iii) 27 + j = -189
Subtract 27 from both sides:
27 + j - 27 = -189 - 27
27 - 27 + j = -189 - 27
j = -216
ANSWER:
i) v = -21
ii) h = 26
iii) j = -216
