There always needs to be an explanation so you understand it!
Follow this step by step.
#1. Remove all -1 on both sides.
You are left with 2(x+3)+x=0.
#2. Expand the equation.
2x+6+x=0.
#3. Simplify 2x + 6 + x to 3x + 6.
3x+6=0
#4. Subtract 6 from each side.
3x=−6.
#5. Divide both sides by 3.
x = -6/3.
#6. Simplify 6/3 to 2.
x = 2.
Therefore, you get [tex]\fbox{x = 2}[/tex].
