Question

For 6z=126, Chris wrote that z=756. Explain what Mike’s mistake was. Then tell the correct answer.

Answer 1

Explanation:

6z=126

z = 126 ÷ 6 = 21

Chris's

z = 756

6z= 126

z = 126 × 6 = 756

correct answer = 21

the number 6 is being multiplied with z.So if the number 6 is going to the right side it will divide the number on the right side.

but for chris he multiplied the number on the right side with 6.So that is the mistake.
