Q:
# What is the solution to the system of equations? y = –3x – 2 5x + 2y = 15 (–40, 19) (–19, 55) (19, –40) (55, –19)

Accepted Solution

A:

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 give5x + 2(-3x-2) = 155x-6x-4 = 15-x-4=15solve for x:-4-15 = xx=-19Now substitute x=-19 into equation (1)y = -3x-2 = 57-2 = 55Therefore the solution is (-19, 55)
