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

17 = 13 - 3r Subtract 13 from bith sides: 4 = -3r Divide both sides by -3 : -4/3 = r or r = -1.3...

What you want to do is to try and get all the variables on one side by adding/subtracting. Then get the numbers on the other side and solve.

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

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

how do i solve -3r+3r=-6(7+7r)-7(4-7r)

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

3r-r equals 12 = -9

If that's 3r + 12, that factors to 3(r + 4)

17 = 13 - 3r Subtract 13 from bith sides: 4 = -3r Divide both sides by -3 : -4/3 = r or r = -1.3...

3r - 9r = 18 wright equaton -6r = 18 combine like terms r = -3 solve

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

(3r + 18)/12 = (4r - 48)/4Multiply both sides by 12: (3r + 18) = 3*(4r - 48)or: 3r + 18 = 12r - 144Subtract 3r from both sides: 18 = 9r - 144Add 144 to both sides: 162 = 9rDivide both sides by 9: 18 = rAnswer: r = 18

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

It is 12r - 20 or 4*(3r - 5)
