Solve : (9 - 3y)/(1 - 9y) = 8/5

Solution:

Given, the equation is (9 - 3y)/(1 - 9y) = 8/5

We have to solve the equation

On solving the equation for y,

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

On cross multiplication,

5(9 - 3y) = 8(1 - 9y)

5(9) - 5(3y) = 8(1) - 8(9y)

45 - 15y = 8 - 72y

By transposing,

45 - 8 = -72y + 15y

37 = -57y

-y = 37/57

y = -37/57

Therefore, the value of y is -37/57
