Chapter 1: Q62. (page 25)

Solve each equation or formula for the specified variable.
$x = \frac{y}{y + 4}$ , for y.

Short Answer

Expert verified

The required answer is $x y + 4 x = y$ .

Step by step solution

Step 1- Determine the approach that can be used

Multiplication of the denominator $y + 4$ on both the sides will help to isolate the variable y.

Step 2- Isolate the variable y

Perform multiplication of $y + 4$ on both the sides of the equation.

$\begin{matrix} x (y + 4) = \frac{y}{y + 4} (y + 4) \\ x y + 4 x = y \end{matrix}$

Step 3- Make the conclusion

As the variable y is isolated so the value equivalent to it represents its value.
