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
X = number. 4X + 9 = 2X - 15 ===========
7
Then the number is 3
9+4x=2x-1 2x=-10 x=-5
18
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
Five more than twice a number is -13 find the number
20
X = number. 4X + 9 = 2X - 15 ===========

Let's call "a number" x. Then 5 more than twice x is 5 + 2x.
It is when the number is -5. I'm so smart.
2n + 2 = 2(n + 1)Since you have been given that it is twice a variable with the variable only, you have 2n, and adding 2 yields 2n + 2, or 2(n + 1).
Then the number is 3
8 more than twice a number d
9+4x=2x-1 2x=-10 x=-5
