Question

On solving x +y =14 and x -y =4, we get

a.
x =5, y =6

b.
x =4, y =2

c.
x =9, y =5

d.
none of these

Answer 1

Answer:

x+y=14

x-y=4

adding,2x=18

x=18/2=9

y=14-9=5

answer c is correct

x=9 , y=5

Answer 2

Answer:

$\mathtt\pink{SOLUTION:-}$

$\mathtt\purple{ \: \: x + y = 14}\\ \mathtt \purple{x - y = 4}$

$_________$

$\mathtt\purple{ 2x = 18}$

$_________$

$\mathtt \purple{2x = 18}$

$\mathtt \purple{x = \frac{18}{2} }$

$\mathtt \purple{x = 9}$

$\: \: \: \: \: \: \: \: \: \: \: \: \:$

$\mathtt\purple{x - y = 4}$

$\mathtt\purple{y = 9 - 5}$

$\mathtt\purple{y = 4}$
