find the value of x and y.​

Answer 1

Answer:

$x = \frac{14}{3} \\ y = \frac{1}{3}$✔✔

Step-by-step explanation:

$we \: use \: substitution \: method \: to \: solve \: this \\ x + y = 5 \\ x = 5 - y - - - - - - (1) \\ x - 2y = 4 - - - - - (2) \\ putting \: value \: of \: x \: in \: (2) \\ 5 - y - 2y = 4 \\ - 3y = 4 - 5 \\ y = \frac{1}{3} \\ putting \: value \: of \: y \: in \: (1) \\ x + \frac{1}{3} = 5 \\ x = 5 - \frac{1}{3} \\ x = \frac{15 - 1}{3} \\ x = \frac{14}{3}$
