X = number.
4X + 9 = 2X - 15
===========
14 more then a number cubed minus twice the number
3*(n - 5) = 2*n + 11
9+4x=2x-1 2x=-10 x=-5

Let's name the first number "X" and the other number "Y" thus: 2X+5Y is the same thing as twice a number more than five times another
Twenty more than twice a number is 52
14 more then a number cubed minus twice the number
It is when the number is -5. I'm so smart.
9+4x=2x-1 2x=-10 x=-5
3*(n - 5) = 2*n + 11
