I will try it with x=20, y=15
From this, you can supply coefficients and calculate the right hand side from the given values of x and y.
I choose coefficients 2 and -3 to give
2x-3y=2*20-3*15=-5
I choose again coefficients, 3 and -1 to give
3x-y=3*20-1*15=45
So my equations are
2x-3y=-5
3x-y=45
Then I would proceed to solve for x and y, which should give me x=20 and y=15, as expected.
how to you solve for x and y so they give you x=20 and y=15
