In this question:
For the first seat, that is, the driver seat, 4 possible people can sit.
For the remaining 7 seats, the number of ways in which the people can sit is an arrangement of 7 elements. So

<u>Answer:</u>
(x, y) = (-2, 2)
<u>Step-by-step explanation:</u>
We are given the following two equations which we are to solve using the substitution method:
--- (1)
--- (2)
From equation (1):

Substituting this value of x in (2) to get:
[/tex]
y = 2
Substituting the value of y in (1) to get x:
x = -2
Therefore, (x, y) = (-2, 2).
-1.5 + k is the same thing as k - 1.5
and if we want to get k all by itself, we need to add 1.5 on both sides, not add -1.5
so
-1.5 + k = 8.2
-1.5 + 1.5 + k = 8.2 + 1.5
k = 8.2 + 1.5
k = 9.7
