Answer:
Step-by-step explanation:
the system of equations is:
First, we multiply the second equation by -9:
and now we add this to the first original equation:
we have eliminated the y variable, so we can solve for x:
with this value of x, we substitute it on the second of the original set of equations to find the value of y:
the answer as an ordered pair is:
1. draw a small circle at -5 and shade line to right
2. draw a small circle at 17 and shade line to left
3. draw a small circle at -1 and shade line to left.
