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.

When writing equations:• Same as translating expressions, but this time you will have an

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

MATHO

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

80x = –640

15𝑡=1

b – 7 = –19

5d = 35

–4x = –24

10 = g + 17

y – 17 = –28

16 = g + 17

Partner PracticeWrite an equation for each. Then solve. Which property

justifies your solution?

1. Twelve subtracted from a number equals 25. Find the number.

2. What number decreased by 52 is 12?

Partner PracticeWrite an equation for each. Then solve. Which property

justifies your solution?

1. What number increased by 20 is equivalent to 10?

2. The sum of a number and fifty is eighty. Find the number.

Ticket Out Write as an equation for each. Then Solve. Name the

property that justifies your solution.1. Fourteen times a number is 42. Find the number.

2. One sixth of a number is equivalent to 17. Find the number.

3. Negative three fifths of a number is 15. What is the number?
