Homework: September 17

Today we practiced solving for an unknown à X

Odysseus spent years trying to get home to his wife and family.  He was trapped on an island, fought monsters, and was attacked by the sea.  He had to problem solve to get out of each situation.

Solve for X

Example:    ( 18 + X ) – 16 = 11

1.   ( 5 + X ) + 3 = 9

2.   (7 + X ) + 5 = 22

3.   ( X – 5 ) – 7 = 3

4.   ( X – 10 ) + 6 = 20

5.   ( X * 2 ) = 24

6.   ( X * 3 ) + 6  = 27

7.   ( X * 5 ) – 4 = 9

Challenge: ( 12 – X ) – 7 = 2
