Question

If x + y = 6 and x - y = 4, then find the value of x?​

Answer 1

Answer:

x = 5

Step-by-step explanation:

x + y = 6 –––––––(1)

x – y = 4 –––––––(2)

adding eq (1) and (2)

2x = 10

x = 5

Answer 2

Answer:

x+y = 6 (equation 1)

x-y = 4

x = 4+y ( equation 2)

put equation 2 in equation 1

(4+y) +y = 6

4+y+y = 6

4+2y = 6

2y = 6-4

2y = 2

y = 2/2

y = 1

put y = 1 in equation 2

x = 4+1

x = 5

Ans:- value of x = 5
