Question

How do you simplify `5 (y - b ) + 3b - 6y + 4 (6 + b )`?

Answer 1

`2b-y+24`

Explanation:

Open the brackets and then add or subtract the like variables.

`5(y-b)+3b-6y+4(6+b)`
`5y-5b+3b-6y+24+4b`
`(5y-6y)+(3b+4b-5b)+24`----->re-arranging the like variables
`-y+2b+24`

re-arranging again:
`2b-y+24`
