First, translate it into an algebraic equation:
4 + 5r = -11
Then we subtract 4 from both sides:
4 + 5r - 4 = -11 - 4
Now we can simplify our numbers together:
(4 - 4) + 5r = -11 - 4
0 + 5r = -15
5r = -15
Now we divide both sides by 5:
(5r / 5) = (-15 / 5)
r = -3
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!
The answer is 21 because if 21 is divided by 3 it equals 7 plus 4 equals 11.
-7 + 11 = +4

It is an equation and the value of x is 4
5r + 8 = -12Subtract 8 from each side:5r = -20Divide each side by 5:r = -4
(5r - 4)(5r + 4)
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!
The answer is 21 because if 21 is divided by 3 it equals 7 plus 4 equals 11.
-7 + 11 = +4
