Answer 1

Answer:

2x+4y=22

-2x+2y=+8

6y=30

y=5

now

replace the value of y in equ i

2x +4y =22

2x+20=22

x=1

Answer 2

Answer: x = 1 y= 5

Step-by-step explanation:

2x + 4y = 22 -

2x - 2y = -8

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

0+6y = 30

Y= 30/6= 5

Substituting,

2x+ 4*5= 22

2x+ 20 = 22

2x= 22-20 = 2

X=2/2=1
