I hope you mean "What is the solution for the problem 5R plus 6 equals 36". In that case 5R + 6 = 36 5R = 36 - 6 5R = 30 R = 6

5r + 8 = -12Subtract 8 from each side:5r = -20Divide each side by 5:r = -4

r+5r+5=-25

If: 2p+5r = q Then: p = (q-5r)/2

In a GP each term is the previous term multiplied by a constant. Let the common difference be r, then: x = 5r y = xr = 5rr = 5r² 40 = yr = 5r²r = 5r³ → 5r³ = 40 → r³ = 8 → r = 2 → x = 5 × 2 = 10 → y = 10 × 2 = 20

1)5r+7=13+2r+3r 2)5r+7=13+5r 3)5r's cancel 7=13 4)Subtract thirteen on both sides 7 =13 -13 -13 5)Answer is no solution because -6 doesn't equal to 0. -6=0 NO SOLUTION!!! Have fun with math!

First, translate it into an algebraic equation:4 + 5r = -11Then we subtract 4 from both sides:4 + 5r - 4 = -11 - 4Now we can simplify our numbers together:(4 - 4) + 5r = -11 - 40 + 5r = -155r = -15Now we divide both sides by 5:(5r / 5) = (-15 / 5)r = -3

so 26 = 4r so r = 6½

You have to combine equal terms. -5r-9s+9r+3s-6 = -5r+9r-9s+3s-6 = 4r-6s-6

(5r - 4)(5r + 4)

-7p + 5r - 6p + 3r = -7p - 6p + 5r + 3r = -(7 + 6)p + (5 + 3)r = -13p + 8r

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

5r = 25 is a linear equation in one variable, r. The solution is r = 5.

Combine the ' 9r ' and the ' -5r ' . Replace them with ' 4r '.
