Explanation:

Step 1: Define

13 + a/11 = 7

Step 2: Solve for a

1. Subtract 13 on both sides: a/11 = -6
2. Multiply 11 on both sides: a = -66

Step 3: Check

Plug in a into the original equation to verify it's a solution.

1. Substitute in a: 13 - 66/11 = 7
2. Divide: 13 - 6 = 7
3. Subtract: 7 = 7

Here we see that 7 does indeed equal 7.

∴ a = -66 is the solution to the equation.
