Answer

x = 1.6

y = -2.8

Explanation

The question wants us to solve the simultaneous equation

4y - 3x = -16

8x - 4y = 24

Adding the two equations, we have,

4y - 3x + 8x - 4y = -16 + 24

5x = 8

Divide both sides by 5

(5x/5) = (8/5)

x = 1.6

If x = 1.6,

8 (1.6) - 4y = 24

12.8 - 4y = 24

-4y = 24 - 12.8

-4y = 11.2

y = -2.8

Hope this Helps!!!
