.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 thats what someone else said and it doesn't work!! And I thought -.6 x 2= -1.2 not positive 1.2.
You're right. My sign is wrong.
0.05x-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.
But that still doesn't work in the equation...does it?
Oh I guess it does. Thanks!
