Question

3x-2y=6
solve

Answer 1

You can't solve a single equatuion with two variables and find a solution.
You can solve an equation with 2 variables for one of the variables.

Answer 2

Because you have two unknowns (x and y) and only one equation, you cannot get a number answer
for x. You can only solve for x in terms of y.
.
To get the answer for x, first get rid of the term on the left side that contains the y. Do
this by adding +2y to both sides. On the left side the -2y and the added +2y cancel each
other out. On the right side the addition of +2y results in 2y + 6. So the equation becomes:

3x=y+6
