The answer is the first one, you must always cite your sources, even if you have not directly quoted them. It also adds credibility to your work (this is not the only reason, it is merely an incentive)
Answer:
This solution is incorrect.
Explanation:
We will use the substitution method to solve this equation.
- The first step is to isolate one of the unknowns to find the solution, in which case we will isolate the x.
Then:
x - y = 75
x = 75 + y
- In the second step, we will replace the x found in the second equation to solve the first equation.
x + y = 743
(75 + y) + y = 743
75 + 2y = 743
2y = 743 - 75
2y = 668
y = 668/2
y = 334
- In the third step, we substitute the value of y in any of the questions to find the final result:
x - y = 75
x - 334 = 75
x = 75 + 334
x = 409
Therefore, if x represents the number of tickets sold before the tournament, and y represents the number of tickets sold at the door, and as the values of x = 409 and y = 334, we can conclude that the assistant made a mistake and inverted the values.
