Question

4x-y= -2
2х + Зу = 13

Answer 1

x=1/2

y=4

Explanation:

4x-y=-2

-y=-4x-2

y=4x+2

2x+3y=13

2x+3(4x+2)=13

2x+12x+6=13

14x=7

x=1/2

y=4x+2

y=4(1/2)+2

y=2+2

Y=4

Answer 2

x = 1/2

y = 4

Explanation:

4x - y = -2 --------------------(I)

2x + 3y = 13 --------------------(II)

Multiply equation (I) by 3 and then add

(I)*3 12x - 3y = -6

(II) 2x + 3y = 13 {Now add and so y will be eliminated}

14x = 7

x = 7/14

x = 1/2

Plugin x = 1/2 in equation (I)

`4*(1)/(2)-y = -2`

2 - y = -2

-y = -2 - 2

-y = -4

y = 4
