• Each team will have a chance to discuss the question and devise an answer.

• Once the time has been called, one person will raise the team’s board to reveal your answer.

What property best justifies the statement,

“If x – 9 = 14, then x = 23.”

What property best justifies the statement,

“If 6x=-18, then x = -3.”

Solve the equation:

2x + 7 = 19

Solve the equation:

-3(x + 4) = 18

#5

Solve the equation:

6(x-1)+2 = 44

Josiah is saving up to buy a present for his mom for her birthday. He knows she really wants the new Kindle, and he found one in the sales paper for \$145.
