Answer:

y=2x-5

Step-by-step explanation:

First simplify: y-1=2x-6

y-1=2(x-3)

First simplify and distribute everything.

<u>y-1=2x-6</u>

So, x equals 2 because it got distributed into the numbers inside the parenthesis.  Same with the 2 and -3.  They multiplied to become -6.

Since it's y-1=2x-6, you can simplify it even more so the -1 goes to the other side and turns into positive 1.

<u>y - 1 (+ 1) = 2x -6 (+ 1)</u>

-1(+1)=0 which leaves just the variable y on the <em><u>left side</u></em>.

-6(+1)=-5 which leaves 2x-5 on the <em><u>right side</u></em>.

This results in y=2x-5.  Hope this helped ;)
