Answer 1

x = 14

y = 3

Explanation:

`2x-8y=4\\2(3y+5)-8y=4\\6y+10-8y=4\\-2y+10=4\\-2y=-6\\y=3\\\\x=3y+5\\x=3(3)+5\\x=9+5\\x=14`

Answer 2

y=3
x=14

Explanation:

2x - 8y = 4

x = 3y + 5
2(3y + 5) - 8y = 4
expand
6y+10-8y=4
simplify, collecting like terms
-2y+10=4
take away 10 to get y on its own
-2y=-6
divide -2
y=3
x=3(3)+5
9+5=14
