how do i solve -3r+3r=-6(7+7r)-7(4-7r)

3r - 9r = 18 wright equaton -6r = 18 combine like terms r = -3 solve
4r +3 = 3r-2 r + 3=-2 r=-5 basically collect terms so that you get one coefficient of r (in this case 4r on one side and 3r on the other. To get the three r over to the other side you subtract 3r on both sides.) Then r+ 3=-2, so that's simple algebraic manipulation.
3R is Recycle,Reduce and Reuse
(3r + 2)(r - 5)
r - 10 + 100 - 3r = -2r + 90
