12(3x+x)=5(2x+8)
We move all terms to the left:
12(3x+x)-(5(2x+8))=0
We add all the numbers together, and all the variables
12(+4x)-(5(2x+8))=0
We multiply parentheses
48x-(5(2x+8))=0
We calculate terms in parentheses: -(5(2x+8)), so:We get rid of parentheses
5(2x+8)
We multiply parentheses
10x+40
Back to the equation:
-(10x+40)
48x-10x-40=0
We add all the numbers together, and all the variables
38x-40=0
We move all terms containing x to the left, all other terms to the right
38x=40
x=40/38
x=1+1/19
