We move all terms to the left:
5(x-3)+9x-(2(x+7))=0
We add all the numbers together, and all the variables
9x+5(x-3)-(2(x+7))=0
We multiply parentheses
9x+5x-(2(x+7))-15=0
We calculate terms in parentheses: -(2(x+7)), so:We add all the numbers together, and all the variables
2(x+7)
We multiply parentheses
2x+14
Back to the equation:
-(2x+14)
14x-(2x+14)-15=0
We get rid of parentheses
14x-2x-14-15=0
We add all the numbers together, and all the variables
12x-29=0
We move all terms containing x to the left, all other terms to the right
12x=29
x=29/12
x=2+5/12
