Question 202143: Solve.
0.2x - 4 ≤ 0.8x+5
Add 4 both,
0.2x-4+4 ≤ 0.8x+5+4
0.2x ≤ 0.8x+9
Subtract 0.8x both,
0.2x ≤ 0.8x +9
0.2x- 0.8x ≤ 0.8x+9-0.8x
-0.6x ≤ 9
I got this far but what is next step? Multiplying?
Thank you!!

-----------
-6x<=90 get rid of fractions
6x>=-90 notice change when multiplying by negative number
x>=-15 divide by 6
---------------
You almost had it done.
