It is 4r + 12s
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
(r + 2)(r + 2)
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
Since 81 - 16r^2 is a multiple of both 4 + r and 4 - r, it is automatically the LCM of this problem.
4r+3 = 3-2 4r = 3-3-2 4r = -2 Divide both sides of the equation by 4 to find the value of r: r = - 1/2
Reduce, Reuse, Recycle and Rethink.
3+10-r+6r = -3+9r+0 13+5r = -3+9r 16 = 4r r = 4
Type your answer here... 6R-12 = 2R + 36 subtract 2R from both sides 4R -12 = 36 add 12 to both sides 4R = 48 divide both sides by 4 R = 12

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