x = 40
y = 10
Given:
Pair of linear equations are-
x-3y = 10 and x-7y = -30
To Find:
values of x and y
Solution:
Let,
Now, eq.(1) - (2)
By sub. value of "y" in eq.(1)
_____________________
Let us substitue the values of 'x' and 'y' in eq.(1)
Now, substitue the values of 'x' and 'y' in eq.(2)
Hence, the values of 'x' and 'y' are 40 and 10 respectively!
