Question

How do you solve `3x - 8y = 4` and `2x - 6y = 2`?

Answer 1

These are two linear equations and you may "solve" the system formed by the two together. This means finding a point, of coordinates `x,y`, which is simultaneously solution of the first and second equation:

Now substitute the values for `x=4` and `y=1` into the equations to see if they satisfy them.
