Which ordered pair is the solution to the system of equations?
{−5x−3y=12y=x−12
(3, −9)
(0, −4)
(−6, 6)
(1, −11)
would the answer be (3,-9)?
Is this Q written correctly?
-5x - 3y = 12y
-5x = 15y
x = -3y NONE of the options fit this equation.
I think this is supposed to be
-5x - 3y = 12
y = x - 12
Sub the second equation into the first for y and we have
-5x - 3 ( x - 12) = 12 simplify
-5x - 3x + 36 = 12
-8x + 36 = 12 subtract 36 from both sides
-8x = - 24 divide both sides by -8
x = 3
And y = 3 - 12 = -9
So you are correct!!!!.... (3 , -9) is the solution
