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 + 18)/12 = (4r - 48)/4Multiply both sides by 12: (3r + 18) = 3*(4r - 48)or: 3r + 18 = 12r - 144Subtract 3r from both sides: 18 = 9r - 144Add 144 to both sides: 162 = 9rDivide both sides by 9: 18 = rAnswer: r = 18
9y subtract 11 equals 7
-2=4r+s s=-4r-2 or s=-(4r+2)
4r + 4 = 5r 4r - r = 3r 4r x r = 4r^2 4r/r = 4
It is 4r + 12s
