Answer and explanation:
<h2>X</h2>
3x + 6y = 180  <em>Use the original expression to find x</em>
3x = 180 - 6y  <em>Subtract 6y by both sides</em>
 <em>Divide by 3 to get x</em>
  <em>Divide by 3 to get x</em>
x = 60 - 3y
<h2>Y</h2>
x = 60 - 3y  <em>Use the new expression to find y</em>
x - 60 = - 3y  <em>Subtract 60 by both sides</em>
 <em>Divide by -3 to get y</em>
  <em>Divide by -3 to get y</em>
