-11=18+s/5
That equation has no solution. There is no possible number that's equal to 18 more than itself.
Set up the equation and solve: x + 5 = -13 (next subtract 5 from each side of the equation to solve for x) x = -18
a + 18 = 90 is a linear equation in one variable. Adding both sides by -18, we get a + 18 - 18 = 90 - 18 a = 90 - 18 = 72
To solve the equation "x + (-6) = 12," you need to isolate the variable x by adding 6 to both sides of the equation. This cancels out the -6 on the left side, leaving you with x = 18. Therefore, the value of x that satisfies the equation is 18.

U can subtract 18 from each side of the equation.

You add -18... 18 + y = 32 18 + y + (-18) = 32 + (-18) y = 14
18+y=32 y=14

To solve the equation n + 3x6 = 30, first calculate 3x6, which equals 18. Then subtract 18 from both sides of the equation to isolate n. Thus, n = 30 - 18, which simplifies to n = 12.
Sorry, that is not an equation, since you have not told us what those terms equal. An equation would look like this: x2 + 6x -18 = 0 (but it doesn't have to equal zero, that is just an example of what it might be). Until we have an actual equation, we cannot solve for x. Also note: you can go to the site wolframalpha.com and they can solve equations and graph them for you. Very convenient.
b + 7 = 18 subtract 7 from each side b + 7 - 7 = 18 - 7 b = 11 ----------------check in original equation 11 + 7 = 18 18 = 18 --------------checks
The real equation got messed up when I posted it, the real equation is this: 2x^3 - 11x^2 + 24x - 18 divided by 2x - 3 ^ = to the 3rd and 2nd power.
