Two equations are given below:

m + 3n = 10
m = n − 2

What is the solution to the set of equations in the form (m, n)?

(1, 3)
(2, 4)
(0, 2)
(4, 6)

For this equation, we can just plug in the equation of m in for m. This makes the equation: n - 2 + 3n = 10. We then only have to solve for n. We add 2 to both sides, making it n + 3n = 12, is which is also 4n = 12. We then divide both sides by 4, getting n = 3. The only answer saying n = 3 is the first.
