Answer:
a) and d)
Step-by-step explanation:
Given in the question, 4 equations.
We will find the solution of all one by one to see which equation have a different solution.
a)
y - 5 = -7
y = -7 + 5
y = -2
b)
-y + 4 = 5
-y = 5 - 4
-y = 1
y = -1
C)
(y/-1) – 6 = -5
-y/1 =-5 + 6
-y = 1
y = -1
D)
(y/3) – 5 = -5
y/3 = -5 +5
y/3 = 0
