Question

Which equation has no solution?

A)4(x+2) equals 4(x-3)

B)-2(x+1) equals 3x-2-5x

C)4(x+1)-7x equals -3(x-1)+1

D)-5(x-7) equals 2 (2x+3)+x+7 ​

Answer 1

A

Explanation:

4(x + 2) = 4(x - 3),

4x + 8 = 4x - 12, The 4x from both sides cancel each other out

8 ≠ -12

Answer 2

Answer: Option A

Explanation:

`4\left(x+2\right)=4\left(x-3\right)`

`4x+8=4x-12`

`4x+8-8=4x-12-8`

`4x=4x-20`

`4x-4x=4x-20-4x`

`0=-20`

`\mathrm{The\:sides\:are\:not\:equal}` = No solution
