___________________________

Given :

• Two equations :

x + y = 14 and x - y = 4

To Find :

• Value of x and y

Solution :

• Simply add both the equations :

$\implies \sf x\:+\:y\:+\:x\:-\:y \:=\: 14\:+\:4$

$\implies \sf 2x \:=\: 18$

$\implies \sf x \:=\: \dfrac{18}{9}$

$\implies \sf x \:=\: 2$

$\bigstar \: \sf Now \:, \:value\: of\: y\: : \\ \sf \: 14 \:-\: x \:= \:14 \:-\: 2 \:=\: 12$
