There are two variables but only one equation, so it can't be solved uniquely because there are many solutions. However, we can express y in terms of x and we can show the relationship between x and y.

So y/2=1-x/4; multiply through by 4: 2y=4-x or x=4-2y or y=½(4-x) or x+2y=4. The relationship can be shown graphically as a straight line.Draw a line though the y intercept (y=2) and x intercept (x=4).

That makes no sense :)

Please explain why you think that. The equation can't be solved, but the y intercept can be found. It's just the value of y when x=0. So this is y=2 as mentioned in the solution.

To solve, do the math problem.

I hope I helped! :)
