Answer 2

ANSWER:

Given;

$= > x + y = 10 \\ \: \: \: \: \: \: \: \: y = x + 4$

$= > x + y = 10 \\ \: \: \: \: \: \: \: \: y - x = 4$

$= > x + y = 10 \\ \: \: \: \: \: \: - x + y = 4$

APPLYING ELEMINATION

$= > 2y = 14$

$= > y = 7$

PUTTING THE VALUE OF X

$= > - x + 7 = 4$

$= > - x = - 3$

$= > x = 3$
