Answer

y=72x−5y = 72x - 5

x=5+y72x = \frac{5+y}{72}

Step-by-step solution

4 steps
  1. Identify the given equation.

    The equation provided is:

    72x−y=572x - y = 5
  2. Understand the nature of the problem.

    This is a single linear equation with two variables, xx and yy. A single equation with two variables has infinitely many solutions. To "find xx and yy" in this context means to express one variable in terms of the other.

  3. Express yy in terms of xx.

    To isolate yy, we can rearrange the equation:

    72x−y=572x - y = 5

    Add yy to both sides:

    72x=5+y72x = 5 + y

    Subtract 5 from both sides:

    72x−5=y72x - 5 = y

    So, we have:

    y=72x−5\boxed{y = 72x - 5}
  4. Express xx in terms of yy.

    To isolate xx, we can rearrange the original equation:

    72x−y=572x - y = 5

    Add yy to both sides:

    72x=5+y72x = 5 + y

    Divide both sides by 72:

    x=5+y72x = \frac{5+y}{72}

    So, we have:

    x=5+y72\boxed{x = \frac{5+y}{72}}
