Can someone please help me with this system of equations question giving brainliest

Option b: (-3,1) is the correct answer.

Step-by-step explanation:

Given that:

y=x+4     Eqn 1

-9y = 27+12x     Eqn 2

Using substitution method, putting value of y from Eqn 1 in Eqn 2

-9(x+4)=27+12x

-9x-36=27+12x

Subtracting 12 from both sides

-9x-12x-36=27+12x-12x

-21x-36=27

Adding on both sides

-21x-36+36=27+36

-21x=63

Dividing both sides by -21

Putting x=-3 in Eqn 1

y = -3+4

y = 1

The solution set is (-3,1)

Hence,

Option b: (-3,1) is the correct answer.
