Question 28692
.90(8)+ 0(x) = .70(x+8) 
7.2 = .70x+5.6 
1.6 = 70x 
2.29c = x



First you take .90 and multiply it by 8, as you see you get 7.2. Than you subtract 0x from .70 and get .70+(x+8). Than you distribute, 7.2=.70x+5.6 and than you subtract 5.6 from 7.2 and get 1.6=.70x. And finally you divide 1.6 by .70 and get 2.285 and if you round that up you will get 2.29c=x
