When multiplying or dividing, what happens when you have two negative signs?

• Your answer will be positive

• Your answer will be negative

Solve. -2 + y = -15

• -13

• 13

• -17

• 17

What are the two basic rules for solving algebraic equations?

• Whatever you do to one side of the equal sign, you must copy and do on the other side of the equal sign

• Negative signs can be ignored

• Always start on the left side, regardless of where the variable is

• Always do the opposite operation

y - 33 = -147

• y = 114

• y = -180

• y = 180

• -114

Write an equation for the model above.

• x - 3 = -9

• x - 3 = 9

• 3x + 1 = 9

• 3x - 1 = 9

Which equation is represented by this model? Which value of x makes this model true?

• x - 6 = 13 x = 19

• x + 6 = 13 x = 7

• x + 6 = 13 x = 8

• x - 6 = 13 x = 7
