You can't find two unknowns from one equation, but you can simplify the equation and find one variable in terms of another. Add 2x to both sides of the equation: 6x-2+y=6. Now add 2 to each side: 6x+y=8. If we subtract 6x from each side we get y in terms of x: y=8-6x. For different values of x we can find corresponding values for y; or we can plot a straight line graph which represents the relationship.
