Answer:
(-3, 4)
Step-by-step explanation:
2x = y - 10 (y = x +7) so
2x = x +7 - 10
2x = x -3
x = -3
-3 + 7 = y
4 = y
To find the mid-way number we do this:
find the difference between the highest number and the lowest given number.
Divide the difference by 2
Add that number to the lowest number or subtract that number from the highest number.
20,000 - 4,632 = 15,362

= 7,684
4,632 + 7,684 = 12,316
or (we get the same number)
20,000 - 7,684 = 12, 316
12,316 is between 4,632 and 20,000
