2x plus 3y
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.
The equation for 3y + 3y = -1 is 3y + 3y = -1.
-2x plus 3y equals 1
x = 8, y = -1
Technically, the answer is probably YES, but it is a tautology and, therefore, adds no value.
y = -1
It cannot be factored.
