Question

x+y is equal to 14 And x-y is equal to 4 solve by elemation ​

Answer 1

$x + y = 14 \: \: \: \: \: \: \: - - - (1) \\ x - y = 4\: \: \: \: \: \: \: \: \: - - - (2)$

Now, Subtracting equation (2), from equation (1), we get,

$(x + y) - (x - y) = 14 - 4 \\ \: \: \: \: \: \: \: x + y - x + y = 10 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 2y = 10 \\\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: y = \frac{10}{2} = 5$

From equation (2), we have,

$= > x = 4 + y \\ = > x = 4 + 5 \\ = > x = 9$

Hence,

${ \boxed{x = 9}} \\ { \boxed{y = 5}}$

Answer 2

Answer:

x+y=14

x-y=4

- + -

2y=10

y=5

according to question:

x+y=14

y=5

x+5=14

x=14-5

x=9

answers:

X =9

y = 5
