4x + Y =4 ---eq -1
2x + 8y = 0 --- eq-2
Multiply eq- 2 by 2 you will get
4x + 16y = 0 ---eq-3
Subtract eq-1 from eq-3 you will get
4x + 16y = 0
-4x - Y = - 4
0 + 15y = -4
y = -4/15
Put the value of y in eq 2 you will get
2x + 8(-4/15) = 0
2x -32/15 =0
2x = 32/15
x = 32/(15)(2)
x = 16/15
(x,y) = (16/15, -4/15)
