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
ANSWER
[tex]x = - 7[/tex]
EXPLANATION
The given equation is
[tex]4(3x + 12) = - 36[/tex]
Expand the parenthesis,
[tex]12x + 48 = - 36[/tex]
Group similar terms
[tex]12x = - 36 - 48[/tex]
[tex]12x = - 84[/tex]
Divide both sides by 12
[tex]x = \frac{ - 84}{12} [/tex]
[tex]x = - 7[/tex]
