This can't be solved because we have two variables x and y and only one equation. We need two equations to solve for x and y, but we can write y in terms of x: subtract 4x from each side and we get: 6y=10x+4. This equation can be plotted on a graph as a straight line passing through the intercepts on each axis: the y intercept is 4/6=2/3, and the x intercept is -4/10=-2/5. The x intercept is found by putting y=0 in the equation, and the y intercept is found by putting x=0 in the equation, and solving for x and y.
