find value of x and y​

Answer 1

Answer:

□X=4✔✔

□Y=0✔✔

Step-by-step explanation:

$we \: use \: substitution \: metho d\: to \: solve \: these \: two \: eqn \\ 2x + 4y = 8 \\ 2(x + 2y) = 8 \\ x + 2y = 4 \\ x = 4 - 2y - - - - - (1) \\ again\\ x - 2y = 4 \\ 4 - 2y - 2y = 4 \\ - 4y = 0 \\ y = 0 - - - - - (2) \\ putting \: value \: of \: y \: in \: (1) \\ x = 4 - 2y \\ x = 4 - 2 \times 0 \\ x = 4 - 0 \\ x = 4$
