-- Remember how to find an average:
-- Add up all the items on the list.
-- Divide the sum by the number of items on the list.

-- John's first 3 test scores were 94, 98, and 98 .

-- His score on the 4th test will be 'F' .

-- His average after the fourth test will be

(94 + 98 + 98 + F) / 4 .

-- He wants that average to be 96.

96 = (94 + 98 + 98 + F) / 4

There's your equation.
