1. Answer:

   1:- Let’s solve for y.

   x−y+1=0

   Step 1: Add -x to both sides.

   x−y+1+−x=0+−x

   −y+1=−x

   Step 2: Add -1 to both sides.

   −y+1+−1=−x+−1

   −y=−x−1

   Step 3: Divide both sides by -1

   −y/-1 = −x−1/−1

   2:- Let’s solve for x.

   3x+2y−12=0

   Step 1: Add -2y to both sides.

   3x+2y−12+−2y=0+−2y

   3x−12=−2y

   Step 2: Add 12 to both sides.

   3x−12+12=−2y+12

   3x=−2y+12

   Step 3: Divide both sides by 3.

   3x

   3

   =

   −2y+12

   3

   x=

   −2

   3

   y+4
