    Answer:

    These equations are equivalent because after you solve the equation the answer are the same. For example 2+2 and 3+1 are equivalent. They both equal four. In these problems are x=3 and x=3.5 they are the same beause of the answer on problem 2 6-x. That makes them both have the same answer

    Step-by-step explanation:

    7x-9=12

       +9=+9

       7x=21

       /7=/7

       x=3
