Question

Solve x +y = 14 and x - y = 4​

Answer 1

Step-by-step explanation:

x + y = 14 ....(1)

x - y = 4 ....(2)

(1)+(2) gives

2x + 0 =18

Therefore x=9

(1) implies

9+y=14

y=5

Hence x=9 y=5

Answer 2

Answer:

x + y =14 -- (i)

x-y = 4 -- ( ii )

from ( i ) equation we obtain x = 14 - y ( iii )

putting iii in equation ii

we obtain

(14 - y ) - y = 4

14 - 2y = 4

10 = 2 y

y = 5

put value of y in equation iii

than we obtain x = 9 .

Therefore x = 9 and y = 5.
