Answer: Step 1 is solved incorrectly.
Step-by-step explanation:
-4(3x+6) +6=-30
= -12x-24+6=-30
and not
-12x-12+6=-30.
The real solution is x=1. Here is how:
−4(3x+6)+6=−30
Use the distributive property to multiply −4 by 3x+6.
−12x−24+6=−30
Add −24 and 6 to get −18.
−12x−18=−30
Add 18 to both sides.
−12x=−30+18
Add −30 and 18 to get −12.
−12x=−12
Divide both sides by −12.
x=−12−12
Divide −12 by −12 to get 1.
x=1
