No.
There is not enough information in the equation x + 2y = 2, by itself, to solve it. There are an infinite number of solutions. A second equation, or information to allow a second equation to be derived, must be given to find a solution.

4y+2 = 2y+6 4y-2y = 6-2 2y = 4 y = 2
Subtract by 7x and divide by 2.
2y = 4 (divide both sides by 2 to solve) y = 2
2y(x+2)=
2y = 15 y = 15/2 y = 7.5
