Question

x+ y = 14, x – y = 4 *Find Solution of the following pair of linear equations​

Answer 1

Answer:

1.) 7

2.) -2

Step-by-step explanation:

x +y = 14

x +x = 14

2x=14

x= 14/2

x=7

check

7+7= 14

Answer 2

x+y=14
x-y=4

by interchanging the signs of all variables---of x-y=4
x+y=14
x-y=4
-(x)+(y)=-(4)
then,
x +y=14
-x+y=-4
x&x cancels
14-4=10
y+y=2y

that is 2y=10
y=5
so ,
x= ?
putting values of y in x+y = 14
then
x+5=14
x=14-5
x=9

• x=9
y =5
