If 5x plus 3y equals 13, the x equals 2 and y equals 1. This is because 5x2=10 and 3x1=3, and 10+3=13.
5
13+13=26
273 13+8 = 21 and 13*21 = 273

The answer to the problem of 13 equals -4x plus 9 is x equals -1.
(2,3)
It works out that: x = 3 and y = 2
basically you asked what -28+21 which equals -7
