18) \( 1=\frac{v+11}{18} \)

To solve the equation \( 1=\frac{v+11}{18} \), start by eliminating the fraction. Multiply both sides by 18 to get \( 18 = v + 11 \). Next, subtract 11 from both sides, giving you \( v = 18 - 11 \), which simplifies to \( v = 7 \). So, the value of \( v \) is 7. Now, to check your work, plug \( v = 7 \) back into the original equation: \( 1 = \frac{7+11}{18} \). This simplifies to \( 1 = \frac{18}{18} = 1 \), confirming that your solution is correct!
