Let
be the amount of food needed for one man for one day. At the beginning, we have enough food for 400 men for 40 days, i.e.

After 10 days, the 400 men will have consumed

food, impliying that the food remaining is

If 200 more men join the garrison, there are now 600 men. Each of them requires
food each day, and there are
units of food remaining. They will last
days.
Not on your list, but an easy way is
.. a) swap coefficients of x and y, negating one. (Now you have 2x -3y.)
.. b) set any constant term to zero (now you have 2x -3y = 0)
.. c) translate the line to the point (5, 2) by substituting x ⇒ x-5, y⇒ y-2
2(x -5) -3(y -2) = 0
The way you've been taught, selection C is the proper choice.
Pedro had 1482 hits and Riley had 1200 hits.
Step-by-step explanation:
Given,
Number of base hits = 2682
Let,
Number of Pedro's hits = x
Number of Riley's hits = y
According to given statement;
x+y=2682 Eqn 1
x = y+282 Eqn 2
Putting value of x from Eqn 2 in Eqn 1

Dividing both sides by 2

Putting y=1200 in Eqn 2

Pedro had 1482 hits and Riley had 1200 hits.
