1) -2(3x+1)+2x = -6x -2 + 2x
= -4x -2
2) -10y+4(3-2y) = -10y + 12 - 8y
= -18y + 12
3) -5(2+2x)-3x = -10 -10x -3x
= -10 -13x
4) -3(2x+3)+3(2+3x) = -6x -9 +6 +9x
= 3x - 3
= -4x -2
2) -10y+4(3-2y) = -10y + 12 - 8y
= -18y + 12
3) -5(2+2x)-3x = -10 -10x -3x
= -10 -13x
4) -3(2x+3)+3(2+3x) = -6x -9 +6 +9x
= 3x - 3
