It is a linear equation in the variable r.
r=12 Work: 5r-20=40 5r=60 r=12
r+5r+5=-25
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
If: 2p+5r = q Then: p = (q-5r)/2
5s-r
13r+10=5r-46 r= r = -7
5r + 8 = -12Subtract 8 from each side:5r = -20Divide each side by 5:r = -4
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
5r + r = 6r
-5r + 8r + 5 = 3r +5
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!
