Unit A1.2, Lesson 4: Solving Strategies

Which equation is equivalent to:

2(3x+4) = 4x+12

• 3x+4 = 4x+10

• 6x+4 = 4x+12

• 6x+8 = 4x+12

• 3x+4 = 4x+6

Which equation is equivalent to:

2(2x+3) = 14

• 4x+3 = 14

• 2x+3 = 12

• 2x+6 = 14

• 2x+3 = 7

Multi-step: Part 1

Find the equivalent equation for:

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

• 3x+6-4x = x+2

• 3x+3-2x = x

• 3x+6-2x = x+2

• 3x+3-2x = x+1

Multi-step: Part 2

Which equation is equivalent to:

3x+6-4x = x+2

• 6+7x = x+2

• 3x+2x = x+2

• 6-1x=1x+2

• 3x-10x = x+2

Multi-step: Part 3

Which equation is equivalent to:

6-x = x+2

• 8-x = x

• 6 = 2x+2

• 6+2x=2

• -x = x+4

Multi-step: Part 4

Which equation is equivalent to:

6 = 2x+2

• 6 = x+1

• 8 = 2x

• 3 = 2x

• 4 = 2x

Multi-step: Part 5 (Final step)

What is the solution for the equation:

4 = 2x

Identify the steps to solve for b

• Add 6 to both sides and divide both sides by 5

• Add 6 to both sides and multiply both sides by 5

• Subtract 6 from both sides then multiply both sides by 5

• Subtract 6 from both sides then divide both sides by 5

Solve the following equation:

5x + 15 = 10x - 40

• x = 10

• x = -10

• x = 11

• x = -11
