Question

5. Solve the system of equation x+y=8, X-y=2.​

Answer 1

Answer:

x=8−y. x−y=2. Replace all occurrences of x in x−y=2 x - y = 2 with 8−y . x=8−y. (8−y)−y=2. Subtract y from −y . x=8−y. 8−2y=2. Replace all occurrences of y in x=8−y x = 8 - y with 3 . x=8−(3) y=3.

Answer 2

Answer:

x=5 and y=3

Step-by-step explanation:

substract eq. (ii) from (i)

we get x=5 ,now put the value of x=5 on eq. (i)

we get ,y=3
