Step-by-step explanation:
if you need to graph us desmos graphing its free just plug in you cordinates
First, create an equation with the criteria given.
If we let x be your number,
(
is twice the product of 3 and x, and if it exceeds 
by 10, then we add 10 to to make the two sides of the equation equal.)
Now, solve for
.
If we let x be your number,
(
Now, solve for
