Question

Jessi sold half her comic books. Then, she bought 9 more. She now has 11 total. How many did she begin with?

Answer 1

Answer:X+9=11

9-9|11-9

X=2

Step-by-step explanation:When the beginning number is unknown we use “x” to be a place holder. If she got 9 more books we would add 9 to the equation. Finally if 11 is the total, the end of the equation would equal 11.
