You can see that the term
appears in both equations. In this cases, we can leverage this peculiarity and subtract the two equations to get rid of the repeated term. So, if we subtract the first equation from the second, we have

Now that we know the value of
, we can substitute in any of the equation to deduce the value of
: if we use the first equation, for example, we have

A parallel line is where you slope is the same but a different y-intercept.
y = 2x + 4
Answer:
78
Step-by-step explanation:
for the right side we can just do 14*2 since there are two people per seat and 14 rows
14 *2 is 28
for the left side we just do 14*3 since there are three people per seat and 14 rows
14*3 is 42
Then we have to add the 8 students that can fit in the very back seat
42 + 28 + 8
28 + 8 is 36
42 + 36 = 78
Answer:
The amount of floor Mrs.Stewart needs for
cups of shortening
cups.
Step-by-step explanation:
Mrs.Stewart pie dough needs
cups of shortening for
cups of flour.
Now we assume that the shortening needed for
cups of flour is
cups.
Accordingly we can arrange the ratios.

Plugging the value of
as it is number of cups of shortening Mrs.Stewart have used.
And multiplying both sides with
,we have
Number of cups of flour (x) 
So (x) 
The amount of floor Mrs.Stewart needed for
cups of shortening =
.
Ans:
11 and four twelfths
