0.8x-0.1-0.5x=-0.7
Subtract 0.5x from both sides.
0.3x-0.1=-0.7
Combine 0.8x and -0.5x to get 0.3x.
0.3x=-0.7+0.1
Add 0.1 to both sides.
0.3x=-0.6
Add -0.7 and 0.1 to get -0.6.
x=\frac{-0.6}{0.3}
Divide both sides by 0.3.
x=\frac{-6}{3}
Expand \frac{-0.6}{0.3} by multiplying both numerator and the denominator by 10.
x=-2
Divide -6 by 3 to get -2.
