Question

How do you solve `6x-4y=10` and `5x-7y=1`?

Answer 1

x=3, y=2

Explanation:

It can be solved by elimination method. To eliminate x, multiply the first equation by 5 and the second by 6 and then subtract as follows:

30x-20y=50
30x -42y =6
On subtraction it would be 22y= 44, that gives y=2. On substituting for y in the first equation it would be 6x=18, that gives x=3
