Step-by-step explanation:
Given, .........(1)
and .............(2)
The equation (1) and (2) are 2 variables equation. Because here two unknown quantity present i.e x and y.
To solve the problem we have to let and
so above two equations become
........(3) and
........(4)
Next step, we have to equate the coefficient of either u or v.
For this equation (4) multiply by 2 , then the equation (4) becomes
........(5)
Adding equation of (3) and (5)
Putting the value of in equation (3)
Therefore and
Therefore and
[ since
and
]
⇒ ..........(6) and
................(7)
Adding equation (6) and (7)
Putting the value of x in equation (6) we get
Therefore
and
