Answer:
{x,y} = {6,7}
Step-by-step explanation:
[1] 2x = 12
[1] x = 6
// Plug this in for variable x in equation [2]
[2] (6) - 5y = -29
[2] - 5y = -35
// Solve equation [2] for the variable y
[2] 5y = 35
[2] y = 7
// By now we know this much :
x = 6
y = 7
We are done

The average is found by adding all the temperatures together, then dividing by the number of days.
Since the average for five days was 63, then the total of the temperatures need to equal 63 x 5 = 315.
The total for the first four days was : 56 + 60 + 79 + 70 = 265
The fifth day is 315 - 265 = 50 degrees.
