Question

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

Answer 1

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.

Answer 2

(x ; y) ∈ ∅

Explanation:

x = 3 - 3y

x + 3y = - 6

replace x

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

3 - 3y + 3y = - 6

3 = - 6

(x ; y) ∈ ∅
