Find Three Ordered Pair Solutions 3x-5y=20

$3 x - 5 y = 20$

Step 1

Solve the equation for $y$ .

Subtract $3 x$ from both sides of the equation.

$- 5 y = 20 - 3 x$

Divide each term in $- 5 y = 20 - 3 x$ by $- 5$ and simplify.

Divide each term in $- 5 y = 20 - 3 x$ by $- 5$ .

$\frac{- 5 y}{- 5} = \frac{20}{- 5} + \frac{- 3 x}{- 5}$

Simplify the left side.

Cancel the common factor of $- 5$ .

Cancel the common factor.

$\frac{- 5 y}{- 5} = \frac{20}{- 5} + \frac{- 3 x}{- 5}$

Divide $y$ by $1$ .

$y = \frac{20}{- 5} + \frac{- 3 x}{- 5}$

Simplify the right side.

Simplify each term.

Divide $20$ by $- 5$ .

$y = - 4 + \frac{- 3 x}{- 5}$

Dividing two negative values results in a positive value.

$y = - 4 + \frac{3 x}{5}$

Step 2

Choose any value for $x$ that is in the domain to plug into the equation.

Step 3

Choose $0$ to substitute in for $x$ to find the ordered pair.

Remove parentheses.

$y = - 4 + \frac{3 (0)}{5}$

Simplify $- 4 + \frac{3 (0)}{5}$ .

Multiply $3$ by $0$ .

$y = - 4 + \frac{0}{5}$

Divide $0$ by $5$ .

$y = - 4 + 0$

Add $- 4$ and $0$ .

$y = - 4$

Use the $x$ and $y$ values to form the ordered pair.

$(0, - 4)$

Step 4

Choose $1$ to substitute in for $x$ to find the ordered pair.

Remove parentheses.

$y = - 4 + \frac{3 (1)}{5}$

Simplify $- 4 + \frac{3 (1)}{5}$ .

Multiply $3$ by $1$ .

$y = - 4 + \frac{3}{5}$

To write $- 4$ as a fraction with a common denominator, multiply by $\frac{5}{5}$ .

$y = - 4 \cdot \frac{5}{5} + \frac{3}{5}$

Combine $- 4$ and $\frac{5}{5}$ .

$y = \frac{- 4 \cdot 5}{5} + \frac{3}{5}$

Combine the numerators over the common denominator.

$y = \frac{- 4 \cdot 5 + 3}{5}$

Simplify the numerator.

Multiply $- 4$ by $5$ .

$y = \frac{- 20 + 3}{5}$

Add $- 20$ and $3$ .

$y = \frac{- 17}{5}$

Move the negative in front of the fraction.

$y = - \frac{17}{5}$

Use the $x$ and $y$ values to form the ordered pair.

$(1, - \frac{17}{5})$

Step 5

Choose $2$ to substitute in for $x$ to find the ordered pair.

Remove parentheses.

$y = - 4 + \frac{3 (2)}{5}$

Simplify $- 4 + \frac{3 (2)}{5}$ .

Multiply $3$ by $2$ .

$y = - 4 + \frac{6}{5}$

To write $- 4$ as a fraction with a common denominator, multiply by $\frac{5}{5}$ .

$y = - 4 \cdot \frac{5}{5} + \frac{6}{5}$

Combine $- 4$ and $\frac{5}{5}$ .

$y = \frac{- 4 \cdot 5}{5} + \frac{6}{5}$

Combine the numerators over the common denominator.

$y = \frac{- 4 \cdot 5 + 6}{5}$

Simplify the numerator.

Multiply $- 4$ by $5$ .

$y = \frac{- 20 + 6}{5}$

Add $- 20$ and $6$ .

$y = \frac{- 14}{5}$

Move the negative in front of the fraction.

$y = - \frac{14}{5}$

Use the $x$ and $y$ values to form the ordered pair.

$(2, - \frac{14}{5})$

Step 6

These are three possible solutions to the equation.

$(0, - 4), (1, - \frac{17}{5}), (2, - \frac{14}{5})$

Step 7
