**Ms. Sue**, Wednesday, October 12, 2011 at 7:54pm.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.

**Clare**, Wednesday, October 12, 2011 at 7:57pmNo thats what someone else said and it doesn't work!! And I thought -.6 x 2= -1.2 not positive 1.2.

**Ms. Sue**, Wednesday, October 12, 2011 at 8:01pmYou're right. My sign is wrong.

**Brian**, Wednesday, October 12, 2011 at 8:34pm0.05x-0.6(x+2)=0.08

Multiply all terms by 100

5x-60(x+2)=8

5x-60x-120=8

-55x=128

x= -(128/55)

All you had to do was put the negative sign in the final answer.
