Question

Which equation has no solution?

A
4(x + 3) + 2x = 6 (x + 2)

B
5 + 2 (3 + 2x) = x + 3 (x + 1)

C
5 (x + 3) + x = 4 (x + 3) + 3

D
4 + 6 (2 + x) = 2 (3x + 8)

Answer 1

4(x+3)+2x=6(x+2)

Explanation:

4x+12+2x=6x+12

(Group like terms)

4x+2x-6x=12-12

6x-6x=0

0=0

Answer 2

A, B & D

Explanation:

They have no solution because the variable x in each of the equation cancels out.
