Question

Solve for x. ​ 4(3x+12)=−36 ​ Enter your answer in the box.

Answer 1

ANSWER

$x = - 7$

EXPLANATION

The given equation is

$4(3x + 12) = - 36$

Expand the parenthesis,

$12x + 48 = - 36$

Group similar terms

$12x = - 36 - 48$

$12x = - 84$

Divide both sides by 12

$x = \frac{ - 84}{12}$

$x = - 7$

Answer 2

Multiply the bracket by 4

4(3x+12)=-36

12x+48= -36

12x+48-48= -36-48

12x= -84

divide by 12 for 12x and -84

12x/12= -84/12

x= -7

Answer is x=-7
