Question

Solve this system of equations. Please write your answer as an ordered pair.



x+3y=1

-3x-3y=-15

Answer 1

this time lets set it equal to x
x+3y=1 in slope intercept form it is x=-3y+1
plug in x=-3y+1 to -3x-3y=-15
-3(-3+1)-3y=-15
9-3=6-3y=-15=y=7

Answer 2

plug in y to any of the equations to get x

Answer 3

first equation is easier so x+3(7)=1=x+21=1 x=-20 answer is (-20,7)

Answer 4

Alright
