Question

Solving -4(x+1)-3=-3(x-4) A-19 B19
C2 D0

Answer 1

A. -19

Step-by-step explanation

We want to solve

`- 4(x + 1) - 3 = - 3(x - 4)`

for x.

Expand the parentheses.

`- 4x - 4- 3 = - 3x + 12`

`- 4x - 7 = - 3x + 12`

Group similar terms:

`- 4x + 3x = 12 + 7`

Simplify

`- x = 19`

Divide both sides by -1

`x= - 19`

The correct choice is A.
