3x + 2y = 8 This is an equation. It could be the equation of a line.

If: 3x+2y = 5x+2y = 14 Then: 3x+2y = 14 and 5x+2y =14 Subtract the 1st equation from the 2nd equation: 2x = 0 Therefore by substitution the solutions are: x = 0 and y = 7

3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2

If: 3x+2y = 5x+2y = 7 Then: 3x+2y = 7 and 5x+2y = 7 Subtract the 1st equation from the 2nd equation: 2x = 0 or x = o By substitution: x = 0 and y = 3.5

-3x + 2y = 12-3x + 3x + 2y = 3x + 122y = 3x + 122y/2 = 3x/2 + 12/2y = (3/2)x + 6

2y = 6x+2

2y-3x=4

Both of them are equations!The solution is (x, y) = (2, 1).

3x plus 2y - 3 is an expression. There can be no answer to one expression and one linear equation in two variables.

-3x + 2y = 9 2y = 3x + 9y = 1,5x + 4,5

The equation can be simplified to show a value of Y in terms of X. 3X + 2Y +2 = 4Y + 4 3X + 2 = 2Y + 4 3X -2 = 2Y and 2Y = 3X - 2 means that Y = (3/2 X) -1

Multiply the first equation by -3
