Question 216538
The sum of four times a number and 16 is 100. Find the number.


Step 1.  Let x be the number


Step 2.  Let 4x be four times the number


Step 3.  Then {{{4x+16=100}}} since the sum of four times a number and 16 is 100.


Step 4.  Solving yields the following steps:


Subtract 16 from both sides of the equation


{{{4x+16-16=100-16}}}


{{{4x=84}}}


Divide by 4 to both sides of equation


{{{4x/4=84/4}}}


{{{x=21}}}


Step 5.  ANSWER:  The number is 21.


I hope the above steps were helpful.
