4(3+x)=36
You Start By Distributing The 4 Into The Parenthesis:
4(3)= 12 4(x)= 4x
Now :
12+4x=36
*Now You Have To Do The Inverse Operation Of The 12 To Get It Separate From The Number & Its Variable*
Subtract 12 From Both Sides , Which Gives U:
4x=24
*Now You Divide 4 On Both Sides To Get The Variable By Itself*
Answer: x=6
