Question

How do you solve `4( y + 2) - y = 2( y - 1) + 9`?

Answer 1

`y=-1`

Explanation:

1. Distribute
   `4(y+2)-y=2(y-1)+9`
   `4y+8-y=2y-2+9`
2. Combine like terms
   `4y+8-y=2y-2+9`
   `{4y-y}+8={-2+9}+2y`
   `3y+8=7+2y`

3. Carry Over
   `3y+8=7+2y`

   `y+8=7`
   4. Solve
   `y+8=7`

   `y=-1`
