s = -2 -4r

if you have 12r and you minus 4r it doesn't equal 48. it would equal 8r to find out what r is i would have to see the whole problem

32 - 21 = 11

7r = 3r - 527r (- 3r) = 3r - 52 (- 3r)4r = - 524r / 4 = -52 / 4r = -13

r=8

-2=4r+s s=-4r-2 or s=-(4r+2)

s = -2 -4r

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

-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

9y subtract 11 equals 7

32 - 21 = 11

7r = 3r - 527r (- 3r) = 3r - 52 (- 3r)4r = - 524r / 4 = -52 / 4r = -13

r=8

63-84 equals = -21

4r + 4 = 5r 4r - r = 3r 4r x r = 4r^2 4r/r = 4

28*21 equals 84
