Cross multiplication!

=

7 × 24 = 8x
168 = 8x
Divide both sides by 8 to isolate x

=

8 and 8 cancels out
21 = x
N=8 is the correct answer
Evaluate -(5)^2. Note that Order of Operations rules (PEMDAS) require that we perform exponentiation before multiplication.
Therefore, we evaluate 5^2 first, obtaining 25, and after that multiply this result by -1.
-(5)^2 = -25
