Question

With solution please thxx

Answer 1

y=4, x=-8

Explanation:

y=1/2x+8 (1)

4x+12y=16 (2)

multiply (1) by 2 we get

2y=x+16

or 2y-x=16

or -x+2y=16 (3)

add (2) and (3)

4x+12y=16

(-x+2y=16 ) x 4

4x+12y=16

-4x+8y=64

we will get 20y=80 by adding both equations

y=4

put the value of y in (1) or (2)

4x+12y=16⇒4x=16-48

x=-8
