help please

anonymous · Answer

Pick one equation to solve for one variable. I suggest the first equation and solve for x because that choice will avoid fractions.

anonymous · Answer

i tried that but i didnt get the answer i needed

anonymous · Answer

What equation did you get?

anonymous · Answer

i got 3y-x=2 idk i cant seem to do because i dont know how

anonymous · Answer

Go back to the first equation:
$$3y-x-1=0$$
and solve for x using inverse operations.

anonymous · Answer

Solve for x means to isolate x.

anonymous · Answer

Inverse operations means if a number is added, then subtract it from both sides.
If the number is being multiplied then divide it from both sides.

anonymous · Answer

so how do i get rid of y

anonymous · Answer

You don't get rid of it - you move it to the other side. The idea in this first step is to isolate x.

radar · Answer

One way would be to add x to both sides of 3y-x-1=0

anonymous · Answer

so it would be 3y-1=0+x

anonymous · Answer

Yes.

anonymous · Answer

You can drop the 0.

anonymous · Answer

ok so whats next

anonymous · Answer

Now, replace the x in the other equation with everything that is x equals.
