Answer:
NO SOLUTION
Step-by-step explanation:
We can make this problem easier to understand if we write the system vertically:
2x-y=7
y=2x+3
and then rewrite the first problem in the form y = mx + b:
2x-y=7 ↔ y + 7 = 2x ↔ y = 2x + 7
y=2x+3
Note how these two equations have the same slope, but different y-intercepts. This tells us that the two lines are parallel, which in turn tells us that they never intercept one another.
Thus, this system has NO SOLUTION.
I'm not positive but I think it would be C
(w³+7)/w=(9w²+7)/9
(w³+7)9=(9w²+7)x
9w³+63=9w³+7x
63=7x
x=9
