\( 0=4+\frac{n}{5} \) \( -4=\frac{r}{20}-5 \) Solve each equation. Fill in the missing number.

Solve the equation by following steps: - step0: Solve for \(r\): \(-4=\frac{r}{20}-5\) - step1: Swap the sides: \(\frac{r}{20}-5=-4\) - step2: Move the constant to the right side: \(\frac{r}{20}=-4+5\) - step3: Add the numbers: \(\frac{r}{20}=1\) - step4: Cross multiply: \(r=20\) Solve the equation \( 0=4+\frac{n}{5} \). Solve the equation by following steps: - step0: Solve for \(n\): \(0=4+\frac{n}{5}\) - step1: Swap the sides: \(4+\frac{n}{5}=0\) - step2: Move the constant to the right side: \(\frac{n}{5}=0-4\) - step3: Remove 0: \(\frac{n}{5}=-4\) - step4: Cross multiply: \(n=5\left(-4\right)\) - step5: Simplify the equation: \(n=-20\) Let's solve each equation step by step: 1. **First Equation:** \[ 0 = 4 + \frac{n}{5} \] To isolate \( n \), we can subtract 4 from both sides: \[ 0 - 4 = \frac{n}{5} \implies -4 = \frac{n}{5} \] Next, we multiply both sides by 5 to solve for \( n \): \[ n = -4 \times 5 = -20 \] 2. **Second Equation:** \[ -4 = \frac{r}{20} - 5 \] To isolate \( r \), we first add 5 to both sides: \[ -4 + 5 = \frac{r}{20} \implies 1 = \frac{r}{20} \] Now, we multiply both sides by 20 to solve for \( r \): \[ r = 1 \times 20 = 20 \] Thus, the solutions are: - \( n = -20 \) - \( r = 20 \)
