Answer:
x=-10
Explanation:
We move all terms to the left:
x/2+17-(12)=0
We add all the numbers together, and all the variables
x/2+5=0
We multiply all the terms by the denominator
x+5*2=0
We add all the numbers together, and all the variables
x+10=0
We move all terms containing x to the left, all other terms to the right
x=-10
