One step Equations

8y = 48

y = ?

Select the following basic rules used for solving one step equations?

(2 answers, select both)

• Whatever you do to one side of the equal sign, you must copy and do on the other side of the equal sign

• Negative signs can be ignored

• Always start on the left side, regardless of where the variable is

• Always do the inverse operation

18 = a/2

(remember the fraction bar means division!)

a = ?

• -11

• -13

• 13

• 11

What equation matches this situation?

Q: Robyn had some video games then bought 4 more. Now she has a total of 10 games.

• v - 4 = 10

• v + 4 = 10

• 10 - 4 = v

• Answer not given

The inverse operation of division is ??????????

• addition

• subtraction

• multiplication

• division

Solve for x:

• x = 20
• x = 7
• x = 10
• x = 3

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.

The FIRST step to solving one step equations is ????????

• Use the inverse on both sides to solve

• identify the variable

• find out the operation in the problem

x+ 3=10

• 3

• 10

• 13

• 7
