You subtract 11 from both sides and r equals negative 7. See... r+11=3 -11 -11 r=7
Subtract negative two from negative nine. = Add two to negative nine. = Negative seven.
Set up the equation and solve: x + 5 = -13 (next subtract 5 from each side of the equation to solve for x) x = -18
Subtract by 7x and divide by 2.

You subtract 11 from both sides and r equals negative 7. See... r+11=3 -11 -11 r=7
15+4m=-14m=-16 (subtract 15 from both sides to isolate variable (4m))m=-4 (divide each side to isolate variable from coefficient)
If A is a variable that you are solving for and the problem is A + 5 = 23 then you subtract 5 from both sides to solve for A... A + 5 - 5 = 23 - 5 Simplify... A = 18
9y subtract 11 equals 7
First you must square the 6 which the answer is 36. Then you subtract 36 from 8 and the answer is negative 28. Finally you solve negative 28 minus 28 (-28-28) which equals negative 56 (-56).
Subtract negative two from negative nine. = Add two to negative nine. = Negative seven.
The value of x is negative 9 (-9). First, subtract the -69 from the -177. This yields the answer -108. Now, divide the -108 by 12, which gives you the answer -9
To solve -2 plus 5 equals, it's probably easier to start with the positive number and add the negative number to it. The equation will look like this: 5 + (-2) = Because you are adding a negative number, you actually have to subtract the 2, rather than add it, so your answer will be 3.
Set up the equation and solve: x + 5 = -13 (next subtract 5 from each side of the equation to solve for x) x = -18
Subtract by 7x and divide by 2.
When you have a negative variable in an equation that you are trying to solve for, you multiply each side of the equation by -1. If it is an inequality such as <, you would flip the sign to > and vice versa.
