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.
