If you mean: 6x-y = 33 and 6x+3y = 45
So by eliminating 6x in both equations by subtracting: 4y = 12 => y =3
Therefore by substitution: x = 6 and y = 3
Remember: --y+3y = 4y

By elimination: x = 3 and y = 0
You cannot solve one linear equation in two variables. You need two equations that are independent.

The given expression can't be solved as equations because there are no equality signs.
Yes and it works out that x = 3 and y = 4
