The point (- 3, 2) is a solution to which of the following pairs of equations?
0 2x + 4y = 2 and - 2x + 2y = - 10
2x + 4y = – 2 and - 2x + 2y = 10
2x + 4y = – 2 and – 2x + 2y = - 10
0 2x + 4y = 2 and - 2x + 2y = 10

Answer :

The last one. Indeed : the couple (x,y) = (-3,2)

Lets replace the values :

2*(-3) + 4*2 = 2

-6 + 8 - 2 = -8 + 8 = 0

And -2*(-3) + 2*2 = 10

6+4 -10 = 10-10 = 0

Good Luck
