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
    2--Multiplying by 100 yields
    ...5x - 60x - 120 = 8
    3--Collecting terms, -55x = 128
    4--Therefore x = -128/55
    5--Checking:
    ...05(-128/55) - .6(-128/55 - 1.2 = .08
    ...Multiplying through by 55 yields
    ....05(-128) - .6(-128) - 66 = 4.4
    6----6.4........+.76.8...-66..= 4.4
    ---------76.8 = 76.8

    x = -128/55
