Answer:
-7
Step-by-step explanation:
-3x-(3(4x)+3(3))=96
-3x-(12x+9)=96
-3x-12x-9=96
-15x-9=96
-15x-9=96
Add +9 to -9 and add +9 to 96
-15x+105
[tex]\frac{-15x}{-15} =\frac{105}{-15}[/tex]
[tex]\frac{15x}{15}= \frac{105}{-15}[/tex]
[tex]x= \frac{105}{-15}[/tex]
x=-7
First, expand:
-3x-12x-9 = 96
Simplify:
-15x-9 = 96
Add 9 to both sides:
-15x = 105
Divide both sides by -15:
x = -7
