Answer: x=4

Step-by-step explanation:

Rearrang the equation to get 3*(x+1)-(15)=0 remove the liked terms to get 3x - 12  =   3 • (x - 4) at the end the equation will be 3 • (x - 4)  = 0 so then solve what’s in the parentheses by doing x-4=0

3(x+1)=15
Divide 3 in both x and 1

3x+3=15

3x=15-3

3x=12

X=12/3

X=4
