Hi this question was already asked but there is still no correct answer. 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.

Ms. Sue
.05x.6(x+2)=.08
0.05x  0.6x + 1.2 = 0.08
0.55x = 0.08  1.2
0.55x = 1.12
x = 1.12 / 0.55
x = 2.036
See if that solution works.

No that's what someone else said and it doesn't work!! And I thought .6 x 2= 1.2 not positive 1.2.

Ms. Sue
You're right. My sign is wrong.

Brian
0.05x0.6(x+2)=0.08
Multiply all terms by 100
5x60(x+2)=8
5x60x120=8
55x=128
x= (128/55)
All you had to do was put the negative sign in the final answer. 
Clare
But that still doesn't work in the equation...does it?

Clare
Oh I guess it does. Thanks!
