Chapter 1: Q16. (page 24)

Solve each equation or formula for the specified variable.
$4 y - 2 n = 9$ , for y.

Short Answer

Expert verified

The required answer is $y = \frac{9 + 2 n}{4}$ .

Step by step solution

Step 1- Add 2n on both sides

Perform addition of 2n on both the sides of equation.

$\begin{matrix} 4 y - 2 n + 2 n = 9 + 2 n \\ 4 y = 9 + 2 n \end{matrix}$

– Isolate the variable y

Perform division of 4 on both the sides of the equation.

$\begin{matrix} \frac{4 y}{4} = \frac{9 + 2 n}{4} \\ y = \frac{9 + 2 n}{4} \end{matrix}$

Step 3- Make the conclusion

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