Hi Kaylee

Since you are working with the sum of two numbers, we can represent the numbers as X & Y.

Assuming that your second sentence is intended to mean four more than the second number...then the first number, X = Y + 4

You are also told that X + 2*Y = 13

Plug in the expression for X in this second equation and you can solve for Y, which you can then use in the expression for X to obtain the value of X.
