Step-by-step explanation:

Step 1: Define

Step 2: Solve for a

Here we see that in order for the proportion to be equal, a must equal 23. Plugging in a back into the proportion should yield us a fraction equivalent to the original fraction.

Solution:

Step-1: Use cross multiplication

Step-2: Simplify both sides

Step-3: Add 6 both sides

Step-4: Divide 2 both sides

Double-check:

Step-1: Substitute the value of a into the proportion

Step-2: Simplify both sides.

The value of a must be 23 to make the proportion true.
