HEYA MATE....

HERE IS YOUR ANSWER......⬇️

Step-by-step explanation:

Question : i} x + y = 14

ii} x - y = 4

Answer : x + y = 14

x = 14 - y

Substituting x = 14 - y in equation ( i )

x - y = 4

( 14 - y ) - y = 4

14 - y - y = 4

14 - 2y = 4

-2y = 4 - 14

-2y = -10

y = - 10/ -2

y = 5

Putting y = 5 in ( ii )

x - y = 4

x = y + 4

x = 5 + 4

x = 9

Hence , x = 9 and y = 5 is the solution of the above equation.
