No.
3x - 5 = 2y3/2X - 5/2 = y
y=-10 sin 5x sin 5x=y/-10 x=asin(y/-10)/5
if you mean 5x -2y = 10 then y = 2.5x -5

This cannot be solved. It needs 2 equations to solve for 2 unknowns.
y = 5x^3 - 45x is a polynomial equation that crosses the y axis at x=3.
y = 2x -1 y = 5x -13 So: 5x -13 = 2x -1 5x -2x = 13 -1 3x = 12 x = 4 and by substituting y = 7

That's not an equation, it is not solveable.
