How to solve One- Step Equations

What is the first step in solving an algebraic equation?

• Move the variable (the letter) to the other side

• Draw a line down the equation sign

• Add or Subtract the number on the other side

What do you want to leave on one side of the equation by itself?

• The number

• The equal sign

• The variable (the letter)

If the equation is adding 5 (+5) on one side, what are you going to do?

• Add 5

• Subtract 5

• Multiply 5

• Divide 5

True or False: You want to do the OPPOSITE of whatever the equation is showing. (Example: If they are subtracting 7, you will add 7)

• True

• False

What is the correct step to solve for the variable?
15 = m - 5

• add 5 to both sides
• add 15 to both sides
• subtract 15 from both sides
• subtract 5 from both sides

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.
