Best Answer

9r = 3r+6

Subtract 3r from both sides:

6r = 6

Divide both sides by 6 to find the value of r:

r = 1

A math problem

3r + 3r + 2t = 6r + 2t

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

3r+10=5r-46 --> add 46 to both sides 3r+10+46=5r-46+46 3r+56=5r --> subtract 3r from both sides 3r+56-3r=5r-3r 56=2r --> divide both sides by 2 56/2=2r/2 28=r

(3r - 2)(3r - 2) or (3r - 2) squared.

(3r + 2)(r - 5)

If: -5 = 7+3r then the value of r works out as -4

3r-2 for r=65

-5 = 7 + 3r | subtract 7 -12 = 3r | divide by 3 -4 = r

3r + 3r + 2t = 6r + 2t

9r = 3r + 6 subtract 3r from both sides 6r = 6 divide both sides by 6 r=1 ■

3r-r equals 12 = -9

No, it's simply 3r, because multiplication (r multiplied by 3) comes first in the order of operations.

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

3r+10=5r-46 --> add 46 to both sides 3r+10+46=5r-46+46 3r+56=5r --> subtract 3r from both sides 3r+56-3r=5r-3r 56=2r --> divide both sides by 2 56/2=2r/2 28=r
