Let n be a number
2n - 3 = 55
Add 3 to both sides
2n + (-3 + 3) = 55 + 3
2n = 58
Divide 2 to both sides
2n/2 = 58/2
n = 29
Hope this helped!

Answer:
She earned $20 in tips.
Step-by-step explanation:
First, you need to work out how much pay she'd get for 12 hours work:
12 x $11.25 = $135 for 12 hours work
Then, find out 2/5 of $11.25 to find out how much she would get for the 2/5 of an hour she worked:
2/5 of $11.25 = $4.50
Add both these sums together to get her total pay for hours worked:
$135 + $4.50 = $139.50
Subtract that sum from her total pay to find out how much money she earned in tips:
$159.50 - $139.50 = <u>$20</u>
I really do not get it . It’s this a question ? If so can you be a little more specific .
