Solve the fair
حلم
linear equation
x + y =14 and x-y=4​

Answer 1

Answer:

$x = 9 \: and \: y = 5$

Step-by-step explanation:

$x + y = 14 \\ x - y = 4 \\ adding \: both \: the \: equations \: we \: get \\ 2x = 18 \\ x = \frac{18}{2} \\ x = 9 \\ subtracting \: both \: the \: equations \: we \: get \\ 2y = 10 \\ y = \frac{10}{2} \\ y = 5$

Answer 2

Answer:

x=9 , y= 5

Step-by-step explanation:

x+y=14

x-y=4 ( then +y-y cancel together) .

2x = 18

x =9

then y,

x+ y = 14

9 +y = 14

y = 5
