3x - y = 2 y = x - 1 when the expression x-1 is substituted in for y in the first equation, the result is 1.) 2x - 1 = 2 2.) 2x + 1 = 2 3.) 4x + 1 = 2

Hi there~!

Let me help you real quick!

We have:
3x - y = 2
y = x - 1
What we need to do is solve y = x -1 for y

Then substitute x -1 for y in 3x -y =2
3x - y = 2
3x - (x -1) = 2
3x -x + 1 = 2
2x + 1 = 2

So, the correct answer is option 2

I hope this helps.

Please let me know if you have any questions about the answer.

Good luck with your studies!
