The mean is not the same thing as median
mean=78+81+85+87=331
mean=331/4=82.75
median is the middle number, but you have a par set of numbers, so your median will be the middle numbers 78,81,85,87 , which are 81+85=166, 166/2=83
83 is your median

Answer:
(x, y) = (-15, -14)
Step-by-step explanation:
y = x+1
y = 2/3x - 4
Next, we will substitute the value of y (first equation) into the second equation.
x+1 = 2/3x - 4
1/3x + 1 = -4
1/3x = -5
x = -15
So, y = -14
