Answer:
I think that there is indefinite.
Step-by-step explanation:
The reason why is because <em>x and y </em>could be any number
Y = -2x - 4
x + 4y = 19
x + 4(-2x - 4) = 19
x + (-8x) - 16 = 19
-7x - 16 = 19
-7x = 35
-x = 5
x = -5
y = -2x - 4
y = -2(-5) - 4
y = 10 -4
y = 6
Solution set {-5, 6} (C)
$24+$5n=$39
because the 2 purses equal a total of $24
Or even more simplified: $5n = $15
n = 3
