This problem can be easily solved using algebra.

Since James wants to know how many months he will have $810, we need to simplify it in an equation.

Let x = number of months

$360 + $90x = $810

We transfer $360 to the other side and reverse operation

$90x = $810 - $360

Now it is simplified to this

$90x = $450

n order to find the value of x, we divide 90 to both sides

$90x/90 = $450/90

... and arrive at the answer.

X = 5

Therefore, it will take 5 months for James to save in order to get $810 in his bank account.
