Since 4R and R both contain a like term (R), you can combine them:
5R would be 4R plus R simplified

4r + 4 = 5r 4r - r = 3r 4r x r = 4r^2 4r/r = 4
It is 4r + 12s
-2=4r+s s=-4r-2 or s=-(4r+2)
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.
-4r = 8Divide each side of the equation by -4 :r = -2
