Algebraic Equations Quiz

What is the key strategy for solving an equation?

• Rearranging the equation until the unknown value is on one side and the known numbers are on the other side

• Subtracting the known numbers from one side of the equation

• Multiplying the equation by a random number

• Adding the unknown value to one side of the equation

What should you do when you make a change to an equation?

• Only make a change on one side of the equation

• Make a different change on each side of the equation

• Make the exact same change on both sides of the equation

• Ignore the need for balance and make any change you want
