What is x plus 5 over 8?

It could be a mathematical formula. If you equate it to a value, you can solve for X, if you want. For example if (X+5)/8 = 20, then X = 8x20-5, which equals 155. Now, if you mean X+5/8, then if you set it equal to 20 you get X = 20-5/8, which equals 19 3/8 or 19.375. All by itself though, X plus 5 over 8 could be anything. Or nothing.


How do you solve a absolute value equation?

The problem |x|-5=3 is an absolute value equation. to find what x equals you have to get x by itself by adding 5 to each side. |x|-5=3 +5 +5 |x|=8 |x| is equal to 8, but is also equal to -8 because the absolute value bars mean that anything inside them is turned positive. Check your answer by substituting 8 and -8 in for x. |8|-5=3? |-8|-5=3?
