    Question 1 (Essay Worth 6 points) Write an equation that you could solve using these steps: Add 7 to both sides. Then, divide both sides by 4. Explain how you know your answer is right.

    4x - 7 = 21 4x = 28 x = 7 substitute 7 into x for the original equation (4(7) -7 = 21) to check your answer. (Visual of what AravindG is saying).

    wait a second..they said add 7 on both sides in question, so we must subtract 7 from both sides!!
