A system of equations is:
B )
x + y = 375
x = 2 y - 60
We will solve this system:
2 y - 60 + y = 375
3 y = 435
y = 435 : 3
y = 145
x = 375 - 145
x = 230
Allan`s score was 230 and Dave`s score was 145.
Answer:
b. 
Step-by-step explanation:
Given expression is:

Let us factorize the numerator using the formula:


Since x ≠ 3, let us cancel the common factor x - 3 in the numerator and in the denominator.
So,
