20-y=-\left(1.5y-2\right)
Use the distributive property to multiply 2 by 10-0.5y.
20-y=-1.5y-\left(-2\right)
To find the opposite of 1.5y-2, find the opposite of each term.
20-y=-1.5y+2
The opposite of -2 is 2.
20-y+1.5y=2
Add 1.5y to both sides.
20+0.5y=2
Combine -y and 1.5y to get 0.5y.
0.5y=2-20
Subtract 20 from both sides.
0.5y=-18
Subtract 20 from 2 to get -18.
y=\frac{-18}{0.5}
Divide both sides by 0.5.
y=\frac{-180}{5}
Expand \frac{-18}{0.5} by multiplying both numerator and the denominator by 10.
y=-36
Divide -180 by 5 to get -36.
