Would -x - 3y = -1 convert into y = -1/3 x - 1/3​
vfiekz [6]

Answer:

Yes, -x - 3y = -1 is the same as y = -1/3x - 1/3

Step-by-step explanation:

-x - 3y = -1

Add x to both sides which gives you

-3y = x-1

Divide both sides by -3 which gives you

y = -1/3x-1/3

Reminder whatever you do to one side you have to do to the other side!

Hope this helps!
