Question

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

Answer 1

8 + x = 100
x = 100 - 8
x = 92 <== ur number

Answer 2

Salutations!

Let the number be
`x`

Your equation would be
`x+8=100`

Now that we have our equation, lets solve this!

Solve this by keeping the variables aside, and the numbers aside


`x=100 -8`

The sign would change because your are isolating the number


`x=100-8`


`x= 92`

Hope I helped (:

Have a great day!
