9w + 45 = 126

Ivan earns $9 per week so we would write it as 9w
Add 45 to it because that is what he also saved
Then he spent those savings which was 126.
Now we can find how many weeks he was saving for.

First minus 45 from both sides
9w = 126 - 45 = 81

The divide both sides by 9
w = 9

Ivan has been saving for 9 weeks
