Solve by Substitution 3x+5y=3 x+2y=0

$3 x + 5 y = 3$ $x + 2 y = 0$

Step 1

Subtract $2 y$ from both sides of the equation.

$x = - 2 y$

$3 x + 5 y = 3$

Step 2

Replace all occurrences of $x$ with $- 2 y$ in each equation.

Replace all occurrences of $x$ in $3 x + 5 y = 3$ with $- 2 y$ .

$3 (- 2 y) + 5 y = 3$

$x = - 2 y$

Simplify the left side.

Simplify $3 (- 2 y) + 5 y$ .

Multiply $- 2$ by $3$ .

$- 6 y + 5 y = 3$

$x = - 2 y$

Add $- 6 y$ and $5 y$ .

$- y = 3$

$x = - 2 y$

$- y = 3$

$x = - 2 y$

$- y = 3$

$x = - 2 y$

$- y = 3$

$x = - 2 y$

Step 3

Divide each term in $- y = 3$ by $- 1$ and simplify.

Divide each term in $- y = 3$ by $- 1$ .

$\frac{- y}{- 1} = \frac{3}{- 1}$

$x = - 2 y$

Simplify the left side.

Dividing two negative values results in a positive value.

$\frac{y}{1} = \frac{3}{- 1}$

$x = - 2 y$

Divide $y$ by $1$ .

$y = \frac{3}{- 1}$

$x = - 2 y$

$y = \frac{3}{- 1}$

$x = - 2 y$

Simplify the right side.

Divide $3$ by $- 1$ .

$y = - 3$

$x = - 2 y$

$y = - 3$

$x = - 2 y$

$y = - 3$

$x = - 2 y$

Step 4

Replace all occurrences of $y$ with $- 3$ in each equation.

Replace all occurrences of $y$ in $x = - 2 y$ with $- 3$ .

$x = - 2 \cdot - 3$

$y = - 3$

Simplify the right side.

Multiply $- 2$ by $- 3$ .

$x = 6$

$y = - 3$

$x = 6$

$y = - 3$

$x = 6$

$y = - 3$

Step 5

The solution to the system is the complete set of ordered pairs that are valid solutions.

$(6, - 3)$

Step 6

The result can be shown in multiple forms.

Point Form:

$(6, - 3)$

Equation Form:

$x = 6, y = - 3$

Step 7

Solve by Substitution 3x+5y=3 x+2y=0
