Step-by-step explanation:

Alex wrote checks on Tuesday for $30 and $40. He also made a deposit in his checking account of $180. Let's solve it step by step:

Alex wrote checks on Tuesday for $30 and $40:

Let's suppose Alex initially had x amount of money out of which $30 & $40 is deducted! so left amount of money is $ (x-70).

He also made a deposit in his checking account of $180:

Out of left money $ (x-70), Alex deposited $180 in account so new money = $ (x-70) + $180 = $ (x+110)

Therefore, Alex finally had $ (x+110) amount of money in his account i. e. He had $100 more then before!
