Chapter 2: Q53. (page 87)

Solve each equation. Check your solution.
$- \frac{2}{5} = - \frac{z}{45}$

Short Answer

Expert verified

The required solution is $z = 18$ .

Step by step solution

Step 1. Write the given information.

The given equation is: $- \frac{2}{5} = - \frac{z}{45}$

Step 2. Calculation.

Consider the given equation,

$- \frac{2}{5} = - \frac{z}{45} \frac{2}{5} (45) = z z = 18$

Step 3. Checking solution.

Substitute $z = 18$ in the given equation, we get

$\begin{array}{l} - \frac{2}{5} = - \frac{z}{45} \\ - \frac{2}{5} = - \frac{18}{45} \\ - \frac{2}{5} = - \frac{2}{5} \end{array}$

Hence, proved.
