Intro Two Step Equations

True or False: To keep an equation balanced, whatever you do on one side of the equals sign has to be done on the other.

• True

• False

• Sometimes

• Divide 2 on both sides

When you're solving an equation, you have to undo the order of operations in the original problem by...?

• Working backwards

• Working in the same order as the original problem

• Working in the opposite order as the original problem

• Guessing until you get it right

True or False: You only have to show inverse operations on one side of the equation.

• True

• False

• Sometimes
