Answer

\( m=5 \), \( v=19 \), \( n=3 \).

Solution

### Equation 1: \( -15=-4m+5 \) 1. Subtract \(5\) from both sides to isolate the term with \(m\): \[ -15-5=-4m \quad \Rightarrow \quad -20=-4m \] 2. Divide both sides by \(-4\) to solve for \(m\): \[ m=\frac{-20}{-4}=5 \] ### Equation 2: \( 10-6v=-104 \) 1. Subtract \(10\) from both sides: \[ 10-6v-10=-104-10 \quad \Rightarrow \quad -6v=-114 \] 2. Divide both sides by \(-6\) to solve for \(v\): \[ v=\frac{-114}{-6}=19 \] ### Equation 3: \( 8n+7=31 \) 1. Subtract \(7\) from both sides: \[ 8n+7-7=31-7 \quad \Rightarrow \quad 8n=24 \] 2. Divide both sides by \(8\) to solve for \(n\): \[ n=\frac{24}{8}=3 \] ### Check - For Equation 1: Substitute \(m=5\) back into the original equation: \[ -4(5)+5=-20+5=-15 \] - For Equation 2: Substitute \(v=19\) back into the original equation: \[ 10-6(19)=10-114=-104 \] - For Equation 3: Substitute \(n=3\) back into the original equation: \[ 8(3)+7=24+7=31 \] All solutions satisfy their respective equations.

Beyond the Answer

To solve the first equation \( -15 = -4m + 5 \), start by isolating \( m \). Subtract 5 from both sides: \( -20 = -4m \). Then divide by -4 to get \( m = 5 \). For the second equation \( 10 - 6v = -104 \), subtract 10 from both sides to find \( -6v = -114 \). Now, divide by -6, giving \( v = 19 \). Finally, for \( 8n + 7 = 31 \), subtract 7 from both sides: \( 8n = 24 \). Divide by 8, which leads to \( n = 3 \). So the missing numbers are \( m = 5 \), \( v = 19 \), and \( n = 3 \). Check: - \( -4(5) + 5 = -20 + 5 = -15 \) (correct!) - \( 10 - 6(19) = 10 - 114 = -104 \) (correct!) - \( 8(3) + 7 = 24 + 7 = 31 \) (correct!)
