Answer 1

Answer:

Here's your Answer☺

➡ 4x-y = 4

4x +2y = -5

- - +

--------------------

-3y = 9

y = -3

➡ For x....

putting the value of y...

➡4(-3)-y =4 = -12 -y =4

= y =-16

Hope it helps ✨☺❤

Answer 2

Step-by-step explanation:

1.

$4x-y=4\\-y=4-4x\\y=-4+4x$

2.

$4x+2y=-5\\putting y from (i)\\4x+ 2(-4+4x)=-5\\4x-8+8x=-5\\12x=-5+8\\12x=3\\x=\frac{3}{12} \\x=\frac{1}{4}$

Now,

$y= -4+4(\frac{1}{4})\\ y= -4+1\\y= -3$
