Solve the following equation
43=j-9
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.
To solve the equation 43 = j - 9, we can isolate the variable j by performing the inverse operation. In this case, since we have j being subtracted by 9, we can reverse this by adding 9 to both sides of the equation.
43 + 9 = j - 9 + 9
On the left side, the sum of 43 and 9 is 52, and on the right side, j - 9 + 9 cancels out, leaving us with just j.
52 = j
Therefore, the solution to the equation is j = 52.
