Answer:
The equivalent to -(-5.25) = 5.25
Step-by-step explanation:
Given

We need to determine the equivalent to -(-5.25)
some of the sign rules are:
+(+) = +
−(−) = +
+(−) = -
−(+) = -
Thus,

Applying the rule: -a(-a) = a

Therefore, the equivalent to -(-5.25) = 5.25
You would get 89/21 and then for a mixed number 4& 5/21
Step 2! The reason for that is the student didnt multiplied (15-2z) with -2. But she should have!
