Question

Solve for each variable in the equations that follow
3x+y=25

Answer 1

If you subtract 3x from both sides you get y=25-3x. If you subtract y from both sides you then you divide both sides by three you get x=25-y/3. You can't get a specific answer

Answer 2

3x + y = 25

To solve for 'y' ...

Subtract 3x from each side: y = 25 - 3x
===========================================

3x + y = 25

To solve for 'x' ...

Subtract 'y' from each side: 3x = 25 - y

Divide each side by 3 : x = (25 - y) / 3
