Question

x-y=7 , x+y=11 solution of this equation​

Answer 1

Step-by-step explanation:

$x - y = 7 \\ x = 7 + y \\ \\ x + y = 11 \\ 7 + y + y = 11 \\ 7 + 2y = 11 \\ 2y = 4 \\ y = 2 \\ so \\ x = 7 + y \\ = 7 + 2 \\ = 9$

Answer 2

Step-by-step explanation:

x-y=7

x= 7+y

put the value of x in this eq. we get

x+y=11

7+y+y =11

7+2y = 11

2y = 4

y = 4/2

y =2

put the value of y in any eq to get ans

x+y=11

x+2 =11

x = 9

so the values of x and y are 9 and2
