Solution: $(1,\frac{1}{3})$

$y = \frac{1}{3} x$ Equation $(1)$ $5x-3y = 4$ Equation $(2)$ Substituting $y$ from Equation $(1)$ in Equation $(2)$ $5x - 3 (\frac{1}{3}x) = 4$ $5x -x = 4$ $4x = 4$ $x = 1$ Substituting $x$ value in Equation $(1)$ $y = \frac{1}{3} x$ $y = \frac{1}{3} (1)$ $y = \frac{1}{3} $ Solution: $(1,\frac{1}{3})$
