The equation is:

.05x-.6(x+2)=.08

Please show the work as well as the answer. Thanks again.

**Dee**, Wednesday, October 12, 2011 at 6:27pmI got 1.12/.55

.05 x-.6x+1.2= .08

-.55x= -1.12

-1.12/-.55

**Clare**, Wednesday, October 12, 2011 at 6:38pmThat 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.

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
