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

• 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

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.

Solve for x in the following equation:

20.5 = x + 4

• 16.5

• 16.05

• 24.5

• 24.05

Solve for z in the following equation:

z - 33 = 147

• z = 114

• z = 177

• z = 180

• no solution

The THIRD 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
