8n - 9 = 17
n - 5 = 8
The number works out as 14

To write the equation based on the given statement, let the number be represented by ( x ). The phrase "20 decreased by two times a number" translates to ( 20 - 2x ), and "10 less than three times the number" translates to ( 3x - 10 ). Therefore, the equation is: [ 20 - 2x = 3x - 10. ]
8<(4n+10)
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).

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.
