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
