Step-by-step Answer:
What is the solution to the system of equations?
y = –3x – 2 ..............(1)
5x + 2y = 15..............(2)
Substitute (1) in (2) to give
5x + 2(-3x-2) = 15
5x-6x-4 = 15
-x-4=15
solve for x:
-4-15 = x
x=-19
Now substitute x=-19 into equation (1)
y = -3x-2 = 57-2 = 55
Therefore the solution is (-19, 55)

<h3>What is Unitary Method?</h3>
Unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Jon spent 1 hour 17 minutes less than Camden
Camden spent 47 minutes less than Pete.
Pete spent 3 hours reading.
Since, pete spent 3 hours. So, Camaden spent
= 3 hours or (180 minutes) - 47 minutes
= 2 hours 13 minutes.
Now, Jon spent = 2 hrs 13 minutes - 1 hour 17 minutes
= 56 minutes
