35 x 20 dollars= 700 dollars. Total cost of all tickets equals 700 dollars
You want to do to one side the same thing you do to the other side.
In order to get the n by itself you divide the 25n by 25. But in order to not change the answer you need to do the same to the 70.

so n=

which can be reduced to

so n=
Your pfp cute what do you need help with again
the y intercept is 3 and the x intercet is 0
this is because it is a straight horizontal line and will never cross the line, meaning there is no slope. So if you were to put this into slope intercept form it would be y=3
