Question

The value of x and y for two equations x+y=5 and 2x-y=4 is​

Answer 1

Answer:

"

Correct answer is 6

Given that,

2x−y=4....(1)

x+y=5....(2)

Adding equation

(1) and (2) we get, 3x=9

x=3 and y=2

Value of xy=3×2=6. "

Answer 2

2x - y = 4____(1.)

x + y = 5____(2.)

y = 5 - x_____(3.)

Place the value of y in equation 1.

2x - ( 5 - x ) = 4

2x - 5 + x = 4

3x - 5 = 4

3x = 4 + 5

x = 9/3

x = 3

Now, place the value of x in equation 3.

y = 5 - x

y = 5 - 3

y = 2

Hence, the value of x is 3 and y is 2.
