Solve the equation.

−18 − 6k = 6(1+ 3k)

• k = -2.67

• k = -1

• k = 1

• k = 6

Solve the equation.

4x + 7 − 6x = 5 − 4x + 4

• x = -4

• x = 3

• x = 1

• x =-1

Solve the equation.

2(3x − 4) = 3x + 1

• x = 3

• x = -2

• x = 1

What is the first step? 

• Get absolute value alone by subtracting 5 from both sides
• Get absolute value alone by dividing by 5 on both sides
• Split into two equations

What is the first step?

• Drop the absolute value bars by splitting into two equations
• Add 2 to both sides

What is the first step?

• Get the absolute value alone by dividing both sides by 5
• Drop the absolute value bars and add 7 and 5 together
• Get the absolute value alone by subtracting 5 from both sides

What is the correct way to write this answer? 

• x < - 8 OR x > - 6
• x < - 8 AND x > - 6
• -8 < x < 6

Which inequality represents the graph?

• -8 < x < -6
• x < - 8 AND x > - 6
• x < - 8 OR x > - 6

Solve this compound inequality 

• -15 < x < 18
• -4 < x < 7
• 4 < x < 7
