Sam is buying packages with 9 beads each. His mom bought him 63 more beads. Now, he has 153 beads. How many packages did he buy? Use algebra to determine the answer.

Sam bought 17 packages of beads.

9x + 63 = 153

9x = 90

x = 10

Sam bought 10 packages of beads, plus the 63 extra beads his mom bought him, for a total of 17 packages.
