Answer:

x = 6

y = -9

Step-by-step explanation:

Here, we want to solve the simultaneous equation using the substitution method

from the first equation;

x = -3-y

Put this in the second equation

-3-y + 2y = -12

-3 + y = -12

y = -12 + 3

y = -9

Recall;

x = -3-y

x = -3-(-9)

x = -3 + 9

x = 6
