Answer and Step-by-step explanation:
The answer you should be getting is [tex]x=-8[/tex]
Step 1: Simplify both the sides of the equation :
[tex](-4)(x)+(-4)(3)=20[/tex] [tex](Distribute)[/tex]
[tex]-4x+-12=20[/tex]
[tex]-4x-12=20[/tex]
Step 2: Add 12 to both the sides :
[tex]-4x-12+12=20+12[/tex]
[tex]-4x=32[/tex]
Step 3: Divide both the sides by -4:
[tex]\frac{-4x}{-4}=\frac{32}{-4}[/tex]
[tex]x=-8[/tex]
Now you've got your answer as -8!
