What is the best way to solve the system of equations below? *

-3x-3y=3

y=-5x-17

a. Elimination

b. Substitution

The best method is substitution

b. Substitution

Step-by-step explanation:

-3x-3y=3

+3x. + 3x

-3 / (-3y) = (3+3x) / -3

y = - 1-x

-1-x=-5x-17

+5x. + 5x

-1+4x = - 17

+1. + 1

4 / (4x) = (-16) / 4

x=-4

y=-1-x

y=-1--4

y=-1+4

y=3
