Solve the following equation

43=j-9

3 answers

Just add 9 to both sides.
Is this correct?
43=52-9
that is correct, but to follow the advice given, you should have taken the following step:

43+9 = j-9+9

That gets rid of the 9 from one side and leaves j all alone:

52 = j

That is the result you wanted, not just rewriting it with the solution inserted. When it says to solve the equation, it means to find the value of j which makes it true.

Then, you can check your result by inserting the answer into the equation, as you did. Since the values now work, your solution for j is correct.
