Question

X = 3 - 3y x + 3y = -6 please explain too

Answer 1

Answer:

(x ; y) ∈ ∅

Step-by-step explanation:

x = 3 - 3y

x + 3y = - 6

replace x

(3 - 3y) + 3y = - 6

3 - 3y + 3y = - 6

3 = - 6

(x ; y) ∈ ∅

Answer 2

Step-by-step explanation:

we have given the value of x is 3 - 3y

$\blue\star$x+3y = -6. (eq 1)

put the value of x in equation 1 we get

$\blue\star$ x + 3y = -6

$\blue\star$ 3-3y+3y.= -6

$\blue\star$ 3 = -6

Hope it helps.
