Krista's bank account has $500. When depositing money today she added four times as many $20 bills as $5 bills. If she added $10 in five dollar bills, how much is in Krista's bank account after this transaction?

Hey bby was a good way i just got

1. use commutative property to reorder the terms.2x+81=0.2. move the constant to right side by adding its opposite on both sides. 2x+81-81=0-81.2x=(-81).3. divide the equation on both sides.2x ÷ 2 = 81 ÷ 2.x = -81/2. your answer is -81/2. if you need to simplify it into a decimal, it’s -40.5.
