The variable, k, is being divided by 11. How should you show your work to isolate the variable?

• Divide both sides by 11

• Multiply both sides by 11.

• Add 11 to both sides.

• Subtract 11 to both sides.

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides
• Subtract 11 from both sides
• Add 11 to both sides
• Divide 3 on both sides.

Solve for v.

• 60
• -3
• 15
• 3

Solve for variable x in the following equation:

11 = 3x + 8x

• x = 1

• x = 2

• x = 3

• x = 4

6 ( 2n + 5 ) = 66

• 3
• 5.08
• 8
• 432

What operation do coefficients perform operationally?

• Addition

• Subtraction

• Multiplication

• Division

Solve:
7w + 5 = 3w - 15

• 5
• -2
• 2
• -5

5h - 6 - h + 10 = 12

• h= 12

• h= 2

• h= 0

• h= 5

Solve for a:

-8(-4+a) + 3(2a+1) = -19

• a = 27

• a = -27

• a = 3.86

• a = 1.67
