x+3y=9
Solve
(First answer gets brainliest)
2 answers:
X + y = 1
x + 3y = 9
Subtract the second equation from the first.
-2y = -8
divide both sides by -2
y = 4
Plug 4 back into either equation and solve for x.
x + y = 1
x + 4 = 1
subtract 4 from each side
x = -3
(-3, 4)
X+3Y=9
-X+Y=1
2Y=8
Y=4
X+4=1
X=-3
