The difference of 9 times a number and 2 is 67, how do you find the number?

Answer 1

Eva Adamson

#x=23/3#

Knowing that a difference is the minus sign, we can write the problem the following way: #9x-2=67#

The rest of the problem is simple algebra to isolate x: #9x=69#

#x=69/9# Simplify the fraction by dividing both numbers by 3:

#x=23/3#

To find the number, divide the difference by 9:

Number = (Difference + 2) / 9

Number = (67 + 2) / 9

Number = 69 / 9

Number ≈ 7.67

The number is approximately 7.67.
