Jerry is using 3 1/2 pounds of ground beef to make hamburgers for a pool party. if he's making quarter-pound hamburgers, how many hamburgers can he make?

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
