Question

Which of the equations have the same solution?

A: 25/2 = 5x

B: 2(x - 7) + 6 = -3

C: 5x + 7(1 - 3x) = -121

Answer 1

A~ 25/2=12.5
12.5/5=2.5
X=2.5
B~x=5/2
C~x=8

Answer 2

A and B have the same solution

Explanation:

A:

25/2=5x

25=10x

25/10=x

2.5=x

B:

2x-14+6=-3

2x-8=-3

2x=5

x=2.5

C:

5x+7-21x=-121

-16x=-128

x=8
