-7.5y-4.5+8y=-6
Use the distributive property to multiply 3 by -2.5y-1.5.
0.5y-4.5=-6
Combine -7.5y and 8y to get 0.5y.
0.5y=-6+4.5
Add 4.5 to both sides.
0.5y=-1.5
Add -6 and 4.5 to get -1.5.
y=\frac{-1.5}{0.5}
Divide both sides by 0.5.
y=\frac{-15}{5}
Expand \frac{-1.5}{0.5} by multiplying both numerator and the denominator by 10.
y=-3
Divide -15 by 5 to get -3.
