Question

multiply both sides :multiply both sides by what?
-4 + \frac{z}{5} = -4
\frac{z}{5} (\quad) = 0 (\quad)

Explanation:

Step1: Identify the equation

The equation is \(-4 + \frac{z}{5} = -4\). We want to eliminate the fraction \(\frac{z}{5}\).

Step2: Determine the multiplier

To solve for \(z\) when we have \(\frac{z}{5}\), we multiply both sides by the denominator of the fraction, which is \(5\). This is because multiplying \(\frac{z}{5}\) by \(5\) gives \(z\) (since \(\frac{z}{5} \times 5 = z\)). So we multiply both sides by \(5\).

Answer:

\(5\)
