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
It is in its simplest form: 4r+r = 5r
4r+4g
-13
(r + 2)(r + 2)
If you mean: 10+4r = 30 then it works out that r = 5
r=8
It simplifies to: 2s+4R
It is (7 + a)r.
4r + 4 = 5r 4r - r = 3r 4r x r = 4r^2 4r/r = 4
-4r+6=14 isn't an inequality, its a linear equation. Anyway... -4r+6=14 (-6) -4r=8 (/4) -r=2 (x-1) r=-2
-2 - 2r or -2(1 - r)
4r + 13 = 57subtract 13 from both sides:4r + 13 - 13 = 57 -134r = 44divide both sides by 4 to solve for r:4r/4 = 44/4r = 11
