Answer:

x = -2 , y = 4

Step-by-step explanation:

given:

5x + 2y = -2                            *4

4x + 3y = 4                             *5

Solving simultaneously,

    20x + 8y = -8 ....eq 1

(-)  20x +15y = 20  ...eq 2

.............................................

-7y = -28

y = -28 / -7

y = 4

  • if y = 4

using equation 2,

20x +15(4) = 20

20x = -40

x = -2
