Question 989555


A number is divided by 2, and then the quotient is added to 8. The result is 33. Find the number. 



We will use x to represent "a number" for the equation {{{(x/2) + 8 = 33}}}.


Solving, {{{(x/2) + 8 = 33}}}  ---> {{{(x/2) = 33 - 8}}} then


{{{(x/2) = 25}}}  --> {{{2*(x/2) = 25*2}}}  ---> {{{x = 50}}} is your answer.



Two is subtracted from a number and then the difference is divided by 3. The result is 30. Find the number.


{{{(x - 2)/3 = 30}}}  ---> {{{3*((x - 2)/3) = 30*3}}}  --> {{{x - 2 = 90}}} 


{{{x = 92}}} is your answer.




A number is multiplied by 2, and then the product is added to 9. The result is 49. What is the number?


{{{2x + 9 = 49}}} ---> {{{2x = 49 - 9}}} ---> {{{2x = 40}}}


then {{{2x/2 = 40/2}}} and {{{x = 20}}} is the final answer.
