Question

51 = 45 + \frac{z}{11}

Explanation:

Step1: Subtract 45 from both sides

To isolate the term with \( z \), we subtract 45 from both sides of the equation \( 51 = 45+\frac{z}{11} \). So we have \( 51 - 45=45+\frac{z}{11}- 45 \), which simplifies to \( 6=\frac{z}{11} \).

Step2: Multiply both sides by 11

To solve for \( z \), we multiply both sides of the equation \( 6=\frac{z}{11} \) by 11. So \( 6\times11=\frac{z}{11}\times11 \), which gives \( z = 66 \).

Answer:

\( z = 66 \)
