Question

5(y-4)=7(2y+1)
I need the answer​

Answer 1

Answer:
`y = -3`

Move all terms containing y to the left, all other terms to the right

Add -14y to each side of the equation

`-20 + 5y + -14y = 7 + 14y + -14y`

Combine like terms: 5y + -14y = -9y

`-20 + -9y = 7 + 14y + -14y`

Combine like terms: 14y + -14y = 0

`-20 + -9y = 7 + 0\\-20 + -9y = 7`

Add '20' to each side of the equation

`-20 + 20 + -9y = 7 + 20`

Combine like terms: -20 + 20 = 0

`0 + -9y = 7 + 20\\-9y = 7 + 20`

Combine like terms: 7 + 20 = 27

`-9y = 27`

Divide each side by -9

`-9y/9=27/-9\\y=-3`
