Solve: $\frac{y}{5 y - 10} - \frac{5}{3 y + 6} = \frac{2 y^{2} - 19 y + 54}{15 y^{2} - 60}$ .

Short Answer

Expert verified

There is no solution.

Step by step solution

Step 1. Given.

The given equation is: $\frac{y}{5 y - 10} - \frac{5}{3 y + 6} = \frac{2 y^{2} - 19 y + 54}{15 y^{2} - 60}$ .

Step 2. To find

We have to solve the given equation.

Step 3. Calculation

LCD of the denominators is $(5 y - 10) (3 y + 6)$ . Multiply both sides by the LCD and then solve the linear equation. After that check if the solution works.

$\frac{y}{5 y - 10} - \frac{5}{3 y + 6} = \frac{2 y^{2} - 19 y + 54}{15 y^{2} - 60} \frac{y}{5 y - 10} (5 y - 10) (3 y + 6) - \frac{5}{3 y + 6} (5 y - 10) (3 y + 6) = \frac{2 y^{2} - 19 y + 54}{15 y^{2} - 60} (5 y - 10) (3 y + 6) y (3 y + 6) - 5 (5 y - 10) = 2 y^{2} - 19 y + 54 3 y^{2} + 6 y - 25 y + 50 = 2 y^{2} - 19 y + 54 3 y^{2} - 19 y + 50 = 2 y^{2} - 19 y + 54 y^{2} - 4 = 0 (y - 2) (y + 2) = 0 y = 2, - 2$

$Plug x = 2 \frac{y}{5 y - 10} - \frac{5}{3 y + 6} = \frac{2 y^{2} - 19 y + 54}{15 y^{2} - 60} \frac{2}{5 (2) - 10} - \frac{5}{3 (2) + 6} = \frac{2 {(2)}^{2} - 19 (2) + 54}{15 {(2)}^{2} - 60} \frac{2}{0} - \frac{5}{12} = \frac{24}{0} Thedenominatorsare0.So x =2 isnotpossible. Plug x = - 2 \frac{y}{5 y - 10} - \frac{5}{3 y + 6} = \frac{2 y^{2} - 19 y + 54}{15 y^{2} - 60} \frac{2}{5 (- 2) - 10} - \frac{5}{3 (- 2) + 6} = \frac{2 {(- 2)}^{2} - 19 (- 2) + 54}{15 {(- 2)}^{2} - 60} \frac{2}{- 20} - \frac{5}{0} = \frac{100}{0} Thedenominatorsare0.So x = - 2 isnotpossible.$

So there is no solution.
