Subtract the equations 3X plus 4Y equals 17 minus (3X plus 2Y equals three)

The problem we are asked to simplify is:

(3x + 4y = 17) - (3x + 2y = 3)

To subtract the equations, we do what we would normally do, combine like terms. This gives us our answer equation of:

(3x - 3x) + (4y - 2y) = (17 - 3)

This gives us our answer of:

2y = 14

But, if we would want to solve it (the question doesn't ask us for this), we find that y = 7 and substitute the value of y in one of the equations to find x.
