elimination means to get rid of one variable by altering the coefficients of variable (by multiplying and diving by some constant number)
in this case, if you just add the two equation, y gets cancelled you get 5x=20 or x=4
put it in any equation to get y (this works because both lines pass through the same point, so they must satisfy that point) to get y=2
Answer:

The number lies
between 2 and 3.
Step-by-step explanation:
She packs 15 pounds of apples equally into 6 bags.
The amount of apples in each bag is gotten by dividing the total amount of apples by the number of bags.
Therefore:
N = 15 / 6 = 5/2 = 
There are
of apples in each bag.
The number lies
between 2 and 3.

Answer:
Step-by-step explanation:
Given: A bushel contains 4 pecks and a peck contains 8 quarts.
i.e. A bush = 4 pecks
A peck = 8 quarts
Then, Number of quarts in 1 bush = 4 (8) =32
Let b = number of bushes and q = number of quarts
Number of quarts(q) in b bushes = 32b
hence, required equation:
which describes the relationship between the number of b bushels and the number of q quarts.
50/5 + 3 * 4/2 - 1 =
10 + 12/2 - 1 =
10 + 6 - 1 =
16 - 1 =
15 <==
