Question

Find a number whose product with 6 is the same as its sum with 60. (Hint: you may want to try guess and check or a table.) Show all steps or reasoning. Be sure to check your answer for reasonableness.

Answer 1

Let the number be = x
Its product with 6 will be = 6x
Its sum with 60 will be = 60 + x

ATQ 6x = 60 + x
6x - x = 60
5x = 60
x = 60/5
x = 12

so the number is 12

Answer 2

CHECKING:

6x = 6*12 = 72
60 + x = 60 + 12 = 72

Answer 3
