• Divide by 5

• Subtract 5

• Multiply by 7

• Subtract 7

What operation would you perform first and then second when solving for m in the following equation?

10 + 7m = 17

• subtract 10, and then divide by 7

• divide by 7, and then subtract 10

• multiply by 7, and then subtract 10

• add 10, and then multiply by 7

Which 2 of the following are basic rules used 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

w + 18 = 27

• 45

• 2

• 9

• 10

Select the equation that best represents the situation: Dr. Lahana takes 30 seconds to solve a Math problem. This is twice as much time as it takes Ms. Rosegreen to solve a Math problem.

• w + 2 = 30

• 2w = 30

• w - 2 = 30

Solve for x:

• x = 20

• x = 7

• x = 10

• x = 3

Solve.

• x = 15

• x = 40

• x = 48

• x = 37

Solve for x:

• x = 20

• x = 7

• x = 10

• x = 3

Solve.

• x = 24

• x = 12

• x = 17.5

• x = 19.5

12(y+2)=6(2y+4)
