Y = 2x + 4 and y = 3x + 1
Therefore, 2x + 4 = 3x + 1
5x + 2y = 7....multiply by -1
-2x + 2y = -14
----------------
-5x - 2y = -7 (result of multiplying by -1)
-2x + 2y = -14
---------------add
-7x = - 21
x = -21/-7
x = 3
5x + 2y = 7
5(3) + 2y = 7
15 + 2y = 7
2y = 7 - 15
2y = - 8
y = -8/2
y = -4
solution is (3,-4)
