PLEASE HELP THIS IS DUE IN 20 MINUTES Solve
y = x+3
by substitution.
(2x + y = -6
What is the solution?
A (-9,-6)
B (-3,0)
C (-1,2)

B. (-3, 0)

Step-by-step explanation:

y = x + 3

2x + y = -6

substitute y = x+3

2x + x +  3 = -6

combine like terms

3x + 3 = -6

subtract 3 from both sides

3x = -9

divide both sides by 3

x = -3

substitute the value ox x into the original equation

2x + y = -6

2(-3) + y = -6

-6 + y = -6

+6          +6

y = 0

hope this helps and have a great  day
