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
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)

-3(x+3y)+2(2x+y) distribute the numbers outside to the numbers inside the parentheses
-3x-9y+4x+2y then combine like terms
6x-3x+6y combine like terms
