Question

Which equations have no solution?

Select all that apply.
A X + 5 = x - 5
B 0.5y = 0
CX-7 = x - 7
D 9(-1 + x) + 1 = 12x + 1
E 8+ 4. f = 4(3+f)

Answer 1

D and B don’t have any solutions

Answer 2

Explanation:

A and E

A

because x+5 = x-5

x-x = -5 -5

0 = -10

E

8 + 4f = 4(3+f)

8 + 4f = 12 + 4f

4f - 4f = 12 - 8

0 = 4

A and E it's not true
