Answer:

Y= x/3 – 4/3

X= 4/3 + y

Step-by-step explanation:

Answer:(0, – )

Step-by-step explanation:Given the 2 equations

3y = x – 4 → (1)

6x – 6y = 8 → (2)

Rearrange (1) expressing x in terms of y by adding 4 to both sides

x = 3y + 4 → (3)

Substitute x = 3y + 4 into (2)

6(3y + 4) – 6y = 8 ← distribute and simplify left side

18y + 24 – 6y = 8

12y + 24 = 8 ( subtract 24 from both sides )

12y = – 16 ( divide both sides by 12 )

y = = –

Substitute y = – into (3) and solve for x

x = 3(- ) + 4 = – 4 + 4 = 0

Solution is (0, – )
