I'm having a very difficult time solving these equations. For some odd reason I keep getting a graph answer. For example, when I try to solve $3x + 2y = 14$; it keeps telling me the answer is, $m=−32$, $b=7$ where $m$ is the slope and $b$ is the $y$-intercept. Which doesn't make sense to me since I have to apply the addition method which I did.
If anyone could help me figure out what I did wrong, so I could go from there, that would be great.
I need to Apply Substitution Method For: $$x + 2y = 4$$ $$2x - y = – 7$$
And I also need to Apply Addition (Elimination) Method For: $$3x + 2y = 14$$ $$5x – 2y = 18 $$
