Warm Up Fri. Sept. 7th• Translate each sentence into an equation.1. Nine times a number t minus twelve equals forty.
2. The sum of x and its square is equivalent to y times z.
3. One-half of the difference of a and b is 54.

Remember to Keep It Balanced!
Whatever you do to one side, you must do to the
other.
Addition Property of Equality• For any numbers a, b and c:
• if a = b, then a + c = b + c
• Examples:1. Solve m – 32 = 18.
2. Solve -18 = p – 12.
UNPACKING
You Do• Solve each equation. Then check your solution.
1. h – 3 = -2
2. p – 5 = 15
3. 20 = y – 8
Subtraction Property of Equality• For any numbers a, b and c
• If a = b, then a – c = b – c
• Example:1. Solve 22 + p = -12.
2. Solve -17 = b + (-4)
UNPACKING
You Do• Solve each equation. Then check your solution.
1. x + 12 = 6
2. z + 2 = -13
Division Property of Equality• For any numbers a, b, and c, with c ≠ 0
• if a = b, then
• Example:1. Solve for y:
2. Solve for v: -30 = -1.5v

Fill in your score card with the integers -12 to 12 (except for 0). You should use each integer ONCE.
When an equation comes up, solve for the variable. Put an X over your solution on your score card.
Goal: Get 5 X’s in a row, column, or diagonal.
a + 5 = 9
