Answer 2

To express x in terms of y in the equation 5x + y = 7, we can follow these steps:

1. Start with the equation: 5x + y = 7.

2. Subtract y from both sides of the equation to isolate the term with x: 5x = 7 - y.

3. Divide both sides of the equation by 5 to solve for x: x = (7 - y) / 5.

Therefore, x can be expressed in terms of y as x = (7 - y) / 5.
