Question

.Find the value of „x‟ and „y‟ in the equations: 2x+y=14 and 2x−y=6.​

Answer 1

Answer:

x=5, y=4

Step-by-step explanation:

2×5+4=14

2×5-4=6

Answer 2

Step-by-step explanation:

take first equation

2x + y = 14

y = 14 - 2x

Now take second equation

2x - y = 6

2x -(14 - 2x) = 6 (Take the value of y from the

above)

2x - 14 + 2x = 6

4x = 6 + 14

4x = 20

x = 20/4

= 5

Now take first equation

2x + y = 14

2 × 5 + y = 14

10 + y = 14

y = 14 - 10

= 4

The value of x = 5 and y = 4
