What are the coordinates of the point on the line $3x + 8y = 60$ such that the $x$-coordinate is $\frac23$ of the $y$-coordinate? Express your answer as an ordered pair.
3x + 8y = 60
Let x = (2/3)y ....so we have
3 (2/3)y + 8y = 60
2y + 8y = 60
10y = 60 divide both sides by 10
y = 6 and x = (2/3) (6) = 4
So the point is ( 4, 6)
