Mathematics
1 answer:
DiKsa [7]2 years ago
4 0

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
