Answer 3

To express y in terms of x or x in terms of y, we need to isolate one variable on one side of the equation. Let's start by expressing y in terms of x:

1. 5x - y = 15

Step 1: Move the term with y to the other side of the equation by adding y to both sides: 5x = y + 15

Step 2: Now, isolate y by subtracting 15 from both sides: y = 5x - 15

So, y is expressed in terms of x as y = 5x - 15.

Next, let's express x in terms of y:

1. 5x - y = 15

Step 1: Move the term with x to the other side of the equation by adding y to both sides: 5x = y + 15

Step 2: Now, isolate x by dividing both sides by 5: x = (y + 15) / 5

So, x is expressed in terms of y as x = (y + 15) / 5.

Both expressions have been derived, and you can use either of them depending on your needs.
