Answer and explanation:

X

3x + 6y = 180  Use the original expression to find x

3x = 180 - 6y  Subtract 6y by both sides

[tex]\frac{3x}{3} = \frac{180}{3} - \frac{6y}{3}[/tex]  Divide by 3 to get x

x = 60 - 3y

Y

x = 60 - 3y  Use the new expression to find y

x - 60 = - 3y  Subtract 60 by both sides

[tex]\frac{x - 60}{-3} = \frac{-3y}{-3}[/tex]  Divide by -3 to get y

[tex]-\frac{x}{3} + 20 = y[/tex]
