Question

Please help me i don't understand. I will give points for explanation too.

Answer 1

y = 4/3x - 5 (first answer on your photo)

Explanation:

4x - 3y = 15

4x - 3y = 15 (we use -4x)

-3y = 15 - 4x (divide by -3)

y = 4/3x - 5

Answer 2

The first one

Explanation:

4x - 3y = 15 .first you subtract the 4x from both sides to get it in correct form

-3y = -4x + 15 . Then you divide both sides by -3 to isolate the y

y = 4/3x - 5 . Then you are left with this answer
