Question

4x-8y=12
14+2x=-6y
plz help​

Answer 1

x=2.7142 y=-2.8571,

Explanation:

given 4x-8y=12............(1)

14+2x=-6y

2x+6y=-14..........(2)

from equ (2) multiply by 2

4x+12y=-28............(3)

substruct (1) and (3)

4x-8y-4x-6y=12-(-28)

-14y=40 ,y=
`(40)/(-14)`=-2.8571

y=-2.8571 put in equ (1)

4x-8(-2.8571)=12

4x=12-22.857=10.8571

x=
`(10.8571)/(4)`

x=2.7142
