18\left(2y-3\right)-14\left(3y-5\right)=28x+21
Multiply both sides of the equation by 28, the least common multiple of 14,2,4.
36y-54-14\left(3y-5\right)=28x+21
Use the distributive property to multiply 18 by 2y-3.
36y-54-42y+70=28x+21
Use the distributive property to multiply -14 by 3y-5.
-6y-54+70=28x+21
Combine 36y and -42y to get -6y.
-6y+16=28x+21
Add -54 and 70 to get 16.
28x+21=-6y+16
Swap sides so that all variable terms are on the left hand side.
28x=-6y+16-21
Subtract 21 from both sides.
28x=-6y-5
Subtract 21 from 16 to get -5.
\frac{28x}{28}=\frac{-6y-5}{28}
Divide both sides by 28.
x=\frac{-6y-5}{28}
Dividing by 28 undoes the multiplication by 28.
x=-\frac{3y}{14}-\frac{5}{28}
Divide -6y-5 by 28.
18\left(2y-3\right)-14\left(3y-5\right)=28x+21
Multiply both sides of the equation by 28, the least common multiple of 14,2,4.
36y-54-14\left(3y-5\right)=28x+21
Use the distributive property to multiply 18 by 2y-3.
36y-54-42y+70=28x+21
Use the distributive property to multiply -14 by 3y-5.
-6y-54+70=28x+21
Combine 36y and -42y to get -6y.
-6y+16=28x+21
Add -54 and 70 to get 16.
-6y=28x+21-16
Subtract 16 from both sides.
-6y=28x+5
Subtract 16 from 21 to get 5.
\frac{-6y}{-6}=\frac{28x+5}{-6}
Divide both sides by -6.
y=\frac{28x+5}{-6}
Dividing by -6 undoes the multiplication by -6.
y=-\frac{14x}{3}-\frac{5}{6}
Divide 28x+5 by -6.
