Equation/Question:
1/2(x-106)=12+7x
Answer/Steps to answer: (x= -10)
1. Simplify 1/2(x-106) to x-106/2.
x-106/2=12 + 7x
2. Multiply both sides by 2.
x−106=24+14x
3. Subtract x from both sides.
−106=24+14x−x
4. Simplify 24+14x-x to 24+13x.
-106=24+13x
5. Subtract 24 from both sides.
-106-24=13x
6. Simplify -106-24 to −130.
-130=13x
7. Divide both sides by 13.
130/13=x
8. Simplify 130/13 to 1010.
-10=x
9. Switch sides.
x=-10

Checking:
1/2(x−106)=12+7x
1. Let x=-10x=−10.1
1/2(−10−106)=12+7×−10
2. Simplify -10-106 to −116.
1/2×−116=12+7×−10
3. Move the negative sign to the left.
-116/2=12+7×−10
4. Simplify 116/2 to 58
−58=12+7×−10
5. Simplify 7×−10 to −70.
−58=12−70
6. Simplify 12-70 to −58.
−58=−58
