5\left(2x-4y+1\right)=3\left(-x-3y-6\right)
Multiply both sides of the equation by 15, the least common multiple of 3,5.
10x-20y+5=3\left(-x-3y-6\right)
Use the distributive property to multiply 5 by 2x-4y+1.
10x-20y+5=3\left(-x\right)-9y-18
Use the distributive property to multiply 3 by -x-3y-6.
10x-20y+5-3\left(-x\right)=-9y-18
Subtract 3\left(-x\right) from both sides.
10x-20y+5-3\left(-1\right)x=-9y-18
Multiply -1 and 3 to get -3.
10x-20y+5+3x=-9y-18
Multiply -3 and -1 to get 3.
13x-20y+5=-9y-18
Combine 10x and 3x to get 13x.
13x+5=-9y-18+20y
Add 20y to both sides.
13x+5=11y-18
Combine -9y and 20y to get 11y.
13x=11y-18-5
Subtract 5 from both sides.
13x=11y-23
Subtract 5 from -18 to get -23.
\frac{13x}{13}=\frac{11y-23}{13}
Divide both sides by 13.
x=\frac{11y-23}{13}
Dividing by 13 undoes the multiplication by 13.
5\left(2x-4y+1\right)=3\left(-x-3y-6\right)
Multiply both sides of the equation by 15, the least common multiple of 3,5.
10x-20y+5=3\left(-x-3y-6\right)
Use the distributive property to multiply 5 by 2x-4y+1.
10x-20y+5=3\left(-x\right)-9y-18
Use the distributive property to multiply 3 by -x-3y-6.
10x-20y+5+9y=3\left(-x\right)-18
Add 9y to both sides.
10x-11y+5=3\left(-x\right)-18
Combine -20y and 9y to get -11y.
-11y+5=3\left(-x\right)-18-10x
Subtract 10x from both sides.
-11y=3\left(-x\right)-18-10x-5
Subtract 5 from both sides.
-11y=3\left(-x\right)-23-10x
Subtract 5 from -18 to get -23.
-11y=-3x-23-10x
Multiply 3 and -1 to get -3.
-11y=-13x-23
Combine -3x and -10x to get -13x.
\frac{-11y}{-11}=\frac{-13x-23}{-11}
Divide both sides by -11.
y=\frac{-13x-23}{-11}
Dividing by -11 undoes the multiplication by -11.
y=\frac{13x+23}{11}
Divide -13x-23 by -11.
