Question

x+y=12;x-y=2, then (x,y)​

Answer 1

Answer:x=7 ,y=5

Step-by-step explanation:

The equation no.1 is x+y=12is added with equation no. 2 x-y=2,x+y+x-y=12+2

2x=14 then x=14/2=7 and ,y=7-2=5

Answer 2

Answer:

x=7, y= 5

Step-by-step explanation:

x+y =12----(1) x-y =2---(2)

x=12-y

put value of x in (2)

12-y-y=2

12-2y =2

12-2=2y

10/2=y

y=5

put value of y in x

x=12-5

x =7
