Roberto decided to get rid of all his baseball cards, so he gave his four friends 32 baseball cards each. How many baseball cards did he have before he giving them to his friends?

a. Write an algebraic equation that represents the scenario.

b. Solve to find the solution.

Step-by-step explanation:

y = number of cards Roberto had in total

x = number of friends he is giving to the cards to

(a)

y = 32x

(b)

To find the number of cards he had in total, just plugin the number of friends he gave his cards to, which was 4 friends

y = 32x

y = 32 (4)

y = 128

Roberto had 128 cards

Y=32 (X), X and Y is your variable for any sort of Linear Equation

Y=32 (4)

Y = 128
