Solve One Variable Expressions

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 in solving the following equation?
3x - 5 = 20

• multiply both sides by 5

• add 5 to both sides

• divide both sides by 5

• subtract both sides by 5

-11 + 3(b + 5) = 7

• 1

• -1

• 3

• -3

7(x + 2) + 3 = 73 Step 1: Distribute
7x + 14 + 3 = 73 Step 2: Combine like terms
7x + 17 = 73 Step 3: Subtract 17
                    Step 4: Divide by 7     

• x = -8

• x = 8

• x = - 12.86

• x = 12.86

8v - 4(v + 8) = 8

• 2

• 10

• 4

• -4 

3x + 2(4x - 4) = 3

• 4

• 3

• 2

• 1

What is the simplified form of this expression
3x+4+5x+3

• 15x

• 8x+7

• 7x+8

Add these expressions
(3x+15) + (4x+13)

• 7x+ 28

• 35x

• x+2

Solve
-5t + 9 = 24

• t = -3

• t = 3

• t = 6

• t = 12

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

• Subtract 11 from both sides

• Divide  - 3 on both sides

• Add 3 to both sides

• Add 11 to both sides
