You can put this solution on YOUR website!
7(3x+4)=8(2x+5)+13
7(3x)+7(4)=8(2x)+8(5)+13
21x+28=16x+40+13
21x+28=16x+53
21x-16x+28=16x-16x+53
5x+28=53
5x+28-28=53-28
5x=25
5x/5=25/5
highlight%28x=5%29
Check, let x=5 and see if the equation balances:
7(3(5)+4)=8(2(5)+5)+13
7(15+4)=8(10+5)+13
7(19)=8(15)+13
133=120+13
133=133 We're right!!!!
Happy Calculating!!!!
