2 over 3 = 18 over x+5...
x=22 because (x+5) needs to equal 27 for the equation to be true.

That equation has no solution. There is no possible number that's equal to 18 more than itself.
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 expression -10 subtracted -9 plus 18, first, we handle the subtraction of -9, which is the same as adding 9. So, -10 + 9 equals -1. Then, adding 18 gives us -1 + 18, which equals 17. Therefore, the final answer is 17.
11x = 20x +1811x-20x=18x(11-20)=18-9x=18x=-2
U can subtract 18 from each side of the equation.
