Answer:
8
Step-by-step explanation:
4+4=8
Both systems will have the same value of x's.
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
Answer:
y = -8
Step-by-step explanation:
y = -10 - x
y = -10 - (-2)
y = -10 + 2
y = -8
