Simplify: -3(x +3y) + 2(2x+y)

Distribute the -3 between both terms in the brackets and the same with the 2 and the second bracket:

x(-3) + 3y(-3) + 2x(2) +y(2)

=-3x -9y +4x+2y Now group the like terms together

= -3x +4x -9y +2y

**= x-7y**

The eNotes rules do not allow me to answer both questions. Please post your other question separately or follow the principles applied here to answer the other question.

`therefore` -3(x +3y) + 2(2x+y)

= **x-7y**

-3(x+3y)+2(2x+y) distribute the numbers outside to the numbers inside the parentheses

-3x-9y+4x+2y then combine like terms

-3x+4x-9y+2y

**x-7y**

6x-3(x-2y)

6x-3x+6y combine like terms

**3x+6y**

`-3(x+3y)+2(2x+y) `

`-3x-9y+4x+2y`

`-3x+4x-9y+2y`

`x-7y`

`6x-3(x-2y)`

`6x-3x+6y `

`3x+6y`
