What is the solution to the system of equations? Y=-3-2. 5x+2y=15

x=-19

y=55

Step-by-step explanation:

y=-3x-2.

5x+2y=15

substitute y into 5x+2y = 15

5x + 2 (-3x-2) = 15

distribute

5x - 6x-4 = 15

combine like terms

-x-4 = 15

add 4 to each side

-x-4+4 = 15+4

-x=19

multiply by - 1

x = - 19

now lets find y

y = - 3x-2

y = - 3 (-19) - 2

y = 57-2

y = 55
