Answer 1

Step-by-step explanation:

(1-9x)/(19-3y)=5/8

by cross multiplying,

8-72x=95-15y

Or, -72x+15y=95-8

Or, -72x+15y-87=0

$\mathtt\color{green}{<strong><em>A</em></strong><strong><em>n</em></strong><strong><em>§</em></strong><strong><em>W</em></strong><strong><em>e</em></strong><strong><em>r</em></strong>}$

Step-by-step explanation:

$\frac{1 - 9x}{19 - 3y} = \frac{5}{8} ...............(1)\\ by \: cross \: multiplication \\ 8(1 - 9x) = 5(19 - 3y) \\ 8 - 72x = 95 - 15y...........(2)$
