(4, 3)

(3, 5)

(-4, 4)

(4, 4)

(4,4)

Step-by-step explanation:

y = 2x - 4 eqn 1

4y = x + 12 eqn 2

From eqn 1 y = 2x - 4; insert in eqn 2

4 (2x-4) = x + 12 (open the bracket)

8x - 16 = x + 12 (taking like figures to the same side, sign changes)

8x - x = 12 + 16

7x = 28

x = 28/7

x = 4

From eqn 1

y = 2x - 4

y = 2(4) - 4

y = 8 - 4

y = 4

(x,y) = (4,4)
