Solve the System of Equations x=5y 3x-15y=0

$x = 5 y$ $3 x - 15 y = 0$

Replace all occurrences of $x$ with $5 y$ in each equation.

Replace all occurrences of $x$ in $3 x - 15 y = 0$ with $5 y$ .

$3 (5 y) - 15 y = 0$

$x = 5 y$

Simplify the left side.

Simplify $3 (5 y) - 15 y$ .

Multiply $5$ by $3$ .

$15 y - 15 y = 0$

$x = 5 y$

Subtract $15 y$ from $15 y$ .

$0 = 0$

$x = 5 y$

$0 = 0$

$x = 5 y$

$0 = 0$

$x = 5 y$

$0 = 0$

$x = 5 y$

Remove any equations from the system that are always true.

$x = 5 y$
