 I can solve equations with integer coefficients and can list my steps in order.

Adding and subtracting one step equations

You will add the opposite to each side and find the value of the integer. Let's try some!

Multiple Choice

What would be the best first step to solving the equation?
-3=x+5

• add 3 to both sides
• subtract 5 from both sides
• add 5 to both sides
• subtract -5 from both sides

If you chose...

subtract 5 from both sides you were right!!!

Multiple Choice

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.
