I can't seem to solve this for x correctly...I got 128 over 55 as an answer which can't be correct. Please help me find the correct answer! Thanks!
The equation is:
.05x.6(x+2)=.08
Please show the work as well as the answer. Thanks again.

I got 1.12/.55
.05 x.6x+1.2= .08
.55x= 1.12
1.12/.55

That doesn't work because .6 x 2= 1.2, not positive 1.2. And it still doesn't equal .08 when you plug it in.

1.05x.6(x+2)=.08
2Multiplying by 100 yields
...5x  60x  120 = 8
3Collecting terms, 55x = 128
4Therefore x = 128/55
5Checking:
...05(128/55)  .6(128/55  1.2 = .08
...Multiplying through by 55 yields
....05(128)  .6(128)  66 = 4.4
66.4........+.76.8...66..= 4.4
76.8 = 76.8
x = 128/55
