`-3(y-3y)+4 =-4(3y-y)+6+13y`
Start by combining like terms inside the parentheses.
`-3(-2y) +4 = -4(2y) +6 +13y`
Multiply terms inside the parentheses by `-3` on the left side of the equation and `-4` on the right side of the equation.
`6y +4 = -8y +6 +13y`
Combine like terms on the right side of the equation.
`6y+4 = 5y +6`
Now subtract `5y` from both sides of the equation.
`1y +4 =6`
Subtract `4` from both sides of the equation.
`1y=2`
`y=2`
Check your solution by plugging your answer into the original equation.
`-3(2-3(2))+4 = -4(3(2)-2) +6 +13(2)`
`-3(-4) +4 = -4(4)+6+26`
`12+4=-16+6+26`
`16= -16+32`
`16=16` Check
The solution is y=2.
