0.86y+2-y=-0.8
Subtract y from both sides.
-0.14y+2=-0.8
Combine 0.86y and -y to get -0.14y.
-0.14y=-0.8-2
Subtract 2 from both sides.
-0.14y=-2.8
Subtract 2 from -0.8 to get -2.8.
y=\frac{-2.8}{-0.14}
Divide both sides by -0.14.
y=\frac{-280}{-14}
Expand \frac{-2.8}{-0.14} by multiplying both numerator and the denominator by 100.
y=20
Divide -280 by -14 to get 20.
