Question 992803
3x - 2y = -14
5x +  y =   6 
*****************************************************
we are asked to check the solution (-2, 4), namely x = -2, y = 4
1) 3x - 2y = -14
3(-2) - 2(4) = -14
-6 -8 = -14
-14 = -14
2) 5x +  y =   6 
5(-2) + 4 = 6
-10 + 4 = 6
-6 NOT = 6
******************************************************
therefore (-2, 4) is not a solution
