How do you more explain how to solve 2x+y=7 for y in the easiest way? I'm very confused? Somebody help me.

Answer 1

For the problem as stated, there is only one basic way to solve it: Subtract 2x from each side, so you have an equation for y:

y = 7 - 2x

If you needed to find an actual value for x, then you would need another equation.
