Question 867947
<pre>
Let the number be x
4 times the number = 4*x
Sum of 4 times number + number itself = 4*x + x = 5*x
This is given to be 10 less than 6 times the number, which can be expressed as 
6*x - 10

Hence the equation is {{{5*x = 6*x - 10}}}
Simplifying, {{{x = 10}}}
The number is {{{highlight(10)}}}
Check: 4 times number = 40. 40 + 10 = 50
6 times number = 60. 60 - 10 = 50. Correct!

Hope you got it :)
