If you would like to solve the system of equations, you can do this using the following steps:
2x - y = -2
x = 14 + 2y
__________
<span>2x - y = -2
</span>2 * (14 + 2y) - y = -2
28 + 4y - y = -2
28 + 3y = -2
3y = -2 - 28
3y = -30 /3
y = -30/3
y = -10
<span>x = 14 + 2y = 14 + 2 * (-10) = 14 - 20 = -6
</span>
(x, y) = (-6, -10)
The correct result would be <span>(-6, -10).</span>
Answer:
$10
Step-by-step explanation:
The hardcover books are $12 each which would be $60 out of the $100. There are four more paperbacks meaning they would be $10 each and cost $40 total.
I hope this helped!!! :)
Answer:
Option D)Neither solution is extraneous.
Step-by-step explanation:
we have

we know that
two possible solutions are x=-7 and x=1
<u><em>Verify each solution</em></u>
Substitute each value of x in the expression above and interpret the results
1) For x=-7


----> is true
therefore
x=-7 is not a an extraneous solution
2) For x=1


----> is true
therefore
x=1 is not a an extraneous solution
therefore
Neither solution is extraneous
