Let's represent the number as (x). The phrase "Eight less than five times a number" can be translated to (5x - 8), and "is seven more than the number" can be translated to (x + 7). Therefore, the algebraic equation representing the given phrase is (5x - 8 = x + 7).
n - 5 = 8
The number works out as 14

Three times a number is 10 less five times the number can be put in the form of an equation that looks like this: 3x = 5x-10. Now just solve for x...
Represent the number by n. The equation is 5n - 1 = 3n +5, and the solution is n = 3.
4x - 8 = 8(x + 2)
