Well, you can't really solve for x or y because you only have one equation, but you could get the line of the straight line:
3x + 2y = 36
2y = 36 - 3x
y = 18 - 3x/2
Where the gradient is -3/2 and the y interecept is 18.

The equation is -2y + 16 = 10
Both of them are equations!The solution is (x, y) = (2, 1).
Double first equation: 10x + 2y = 10Subtract second equation: 7x = 7x = 1, y = 0
4x + 2y = 6 (first equation x 2) 4x + 2y = 6 (second equation rearranged) No unique answer exists
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
