First substitute y=5x+7 so that would turn into 5x+7=6x
Then, isolate/solve for x for 5x + 7 = 6x, in this problem x=7
Substitute x=7 into y=5x+7
y=42
x=7, y=42
(7,42)
The answer is 4140

Finding the equivalent multiplier, it is found that the function for the final price is:
P(x) = 0.68x.
-------------------------------------------
- There is a holiday sale of 20% off the price of x, thus 0.8x is paid, as 1 - 0.2 = 0.8.
- Additionally, there is a coupon of 15% off, thus, 0.85 of 0.8x is paid.
- The equivalent multiplier is:
- Thus, the function for the final price is:
