28y+8-9\left(5-y\right)=-43
Use the distributive property to multiply 4 by 7y+2.
28y+8-45+9y=-43
Use the distributive property to multiply -9 by 5-y.
28y-37+9y=-43
Subtract 45 from 8 to get -37.
37y-37=-43
Combine 28y and 9y to get 37y.
37y=-43+37
Add 37 to both sides.
37y=-6
Add -43 and 37 to get -6.
y=\frac{-6}{37}
Divide both sides by 37.
y=-\frac{6}{37}
Fraction \frac{-6}{37} can be rewritten as -\frac{6}{37} by extracting the negative sign.
