Solution
To evaluate the expression 6 + 7a when a = 2, you substitute the value of a into the expression.
Step 1: Substitute a = 2 into the expression 6 + 7a becomes 6 + 7*2
Step 2: Perform the multiplication 7*2 equals 14
Step 3: Add the results 6 + 14 equals 20
So, the value of the expression 6 + 7a when a = 2 is 20.
