Angela incorrectly claimed the equation \(18 - 9x = 2\) represents the following description: "The difference of nine times a number and 8 is two."

Write the correct equation. What error might Angela have made?

Asked by Ceia24

Answer (3)

the discription is too confusing
so 9 times a number 8 means 9 times 8 which is 72 and is too what. where does the 2 and the 18 come in that is the problem

18-9x=2 18-2=9x 16=9x x=16/9

The correct equation is 9x - 8 = 2. Angela's error was misunderstanding the phrase "the difference of nine times a number and 8" by incorrectly associating it with a separate addition or multiplication. By clarifying the subtraction involved, the correct representation is formed.
