One Step Two Step Equations and Inequalities on Number Line

Solve:
3(x - 2) < 2(x + 9)

• x<24

• x>12

• x<12

• x>24

What would be the solution for the equation?

 3(x-2)=2x+7

• x = 13

• x = 5

• x = 1

• x = 13 /5

Write an equation for the model above.

What equation is modeled? Solve the equation.

In the equation x+7=12 7 is being added to the variable, x. How should you show your work to isolate the variable and solve the equation?

• Subtract 7 from both sides. The solution is x = 5.

• Add 7 to both sides.

  The solution is x = 19.

• Multiply both sides by 7 The solution is x = 84.
