Step-by-step explanation:
Assuming that Justine's score is represented by and Meagan's score is represented by
, we know that
will always be the opposite of
.
To represent opposite, we put a negative sign before the variable.
This makes the current number, even if it's negative, the opposite value.
Let's test it out.
Since Justine's score is -7, substituting it into the equation makes it . We know that two negatives make a positive, so
.
Now let's assume Justine's score is 7. Plugging it into the equation, we get . That's the same thing as

30 = 60% of x
x being our variable, we need to figure out what x equals. Use the formula I put in the attachment. Multiply 30 by 60, and then divide the product by 100. That will give you the answer :)
