Answer:
No
Step-by-step explanation:
A point is a solution to a system of equations if its x and y values can be substituted into both equations and both of the end results are true statements. So, let's substitute the x and y values of (2,-1) into the given equations to see if it's a solution.
1) First, let's try this with 2x-y = 3. Substitute 2 for x and -1 for y in the equation, then simplify:
When simplifying, we got the result of 5 = 3. But 5 doesn't equal 3. Thus, this is a false statement, and the point is not a solution.
