please gelp guys​

Answer 1

Answer:

x = 3 and y = 2

Step-by-step explanation:

2x + y = 8.......1

x + 6y =15........2

Now multiply 2 with 2

2x + y =8

2x + 12y =30

- - -

0x - 11y = - 22

y = 2

Now from 1

2x + 2 =8

2x=6

x = 3

Answer 2

x + y/2=4

x/3 + 2y =5

we can rewrite these equations as

2x + y =8 -( 1)

x + 6y=15 -(2)

now multiply equation (2) by 2

x will get eliminated

so the equation will be

2x + y =8

2x + 12y=30

-11y= -22

so y =2

and x =8-y/2

putting value of y we get value of

x=3

so values of x=3 and y=2

hope it helps you
