A system of equations? Try elimination.

- 2(-3X + Y = 7)

5X + 2Y = 3

6X - 2Y = - 14

5X + 2Y = 3

--------------------------add

11X = - 11

X = - 1

------------Put back in equation to solve for Y

- 3(-1) + Y = 7

3 + Y = 7

Y = 4

-------------check both equations

- 3(-1) + 4 = 7

3 + 4 = 7

top checks

5(-1) + 2(4) = 3

- 5 + 8 = 3

both equations check and the system is consistent
