System of equations please help my teacher sent home a review packet from last year u don't remember this. help me

C

Step-by-step explanation:

Given the 2 equations

3y = x - 2 → (1)

y = - 2x + 4 → (2)

Substitute y = - 2x + 4 into (1)

3(- 2x + 4) = x - 2, that is

- 6x + 12 = x - 2 ( subtract x from both sides )

- 7x + 12 = - 2 ( subtract 12 from both sides )

- 7x = - 14 ( divide both sides by - 7 )

x = 2

Substitute x = 2 into (2) for corresponding value of y

y = - 2(2) + 4 = - 4 + 4 = 0

Thus x = 2 : y = 0 → C

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.
