Question

X+3y=6 x-3y = 12 Using elimination

Answer 1

Answer:

x = 9 ; y = -1

Step-by-step explanation:

because one equation is 3y and the second is -3y they will cancel out (eliminate) so the term y will be gone and you combine (add) the rest of the terms and end up with

$2x=18$

then divide both sides by 2 to get: x = 9

plug in the value of x into one of the original problems

$9+3y=6$

and solve for y

$3y=-3\\y=-1$

if you plug in the values of x and y into the equations it should be true
