Solve One and Two Step Equations with Positive Numbers

What is a two-step equation?

• an algebraic equation that takes you two steps to solve.

• an addition problem with two numbers

• new age subtraction

• an algebraic equation you can solve in only one step

4x = 8

• x = 2

• x = 5

• x = 3

• x = 7

In 6x + 2 = 20 , The x is = 3

• True

• False

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

• Add 3 to both sides

• Add 11 to both sides

• Subtract 11 from both sides

• Divide 3 on both sides

Solve for k:

3k + 5 = 23

• k= 4

• k=0

• k=6

• k=8

The objective when solving an equation is to....

• guess and check.

• hope you get the right answer.

• check the solution.

• isolate the variable.

What is the variable in this equation: 4x + 7 = 23 ?

• 4

• 7

• x

• 23

Solve t + 7 = 14

• t= 8

• t = 7

• t= 14

• t = 6

2d + 7 = 9

• d = 4

• d = 1

• d = 3

• d = 6

What is the first step in solving this equation:
5x + 7 = 12

• Divide by 5
