Question

The sum of eight and a number is one hundred. What is the number?

Answer 1

To work out the answer to this question, you simply have to work it out in reverse. So, one hundred take nine is ninety-two. Therefore the sum of eight and that same number, ninety-two, must be the answer to this question. Hopefully that answers your query!

Answer 2

sum of 2 numbers is the answer / number you get after addiing the 2 numbers

we are told that sum of 8 and another number is 100

so lets call the other number x

so if we put this in an equation

8 + x = 100

we have to make x the subject of the formula as we need to find x

so we have to make x the only term on one side of the equation

for this we carry out the reverse operator for addition of 8 on both sides of the equation

reverse operator for addition is subtraction

x + 8 - 8 = 100 - 8

x = 92

the number is 92
