# The sum of four times a number and 9 is same as one -third that number increased by 31 find number

Dear student,
Le the number be x, therefore from the above information the equation will be
$4x+9=\left(\frac{1}{3}×x\right)+31\phantom{\rule{0ex}{0ex}}4x+9=\frac{x+93}{3}\phantom{\rule{0ex}{0ex}}12x+27=x+93\phantom{\rule{0ex}{0ex}}12x-x=93-27\phantom{\rule{0ex}{0ex}}x=\frac{66}{11}\phantom{\rule{0ex}{0ex}}x=6$

Regards
