Answer:
(2,3)
Step-by-step explanation:
use the equal values method.
set y equal to itself.
y = -2x+7 but also 5x-7
-2x+7=5x-7 ............................. solve the equation
7x=14
x=2
Now substitute the x value into one of the equations given. for example i'll do -2x+7.
-2(2) +7 =y
-4+7=y
3=y
so thats your answer
x=2, y=3

Median is the number in the middle when all the numbers are put in order.
Let's do that first.
30 52 61 65 68 68 69 75 78 85
Now if there's 10 numbers, 2 numbers are in the middle.
By counting in 4 on both sides, we know the two numbers are both 68, so 68 is the median.
