 Given \: \frac{(1-9y)}{(19-3y)} = \frac{5}{8}

/* Doing Cross multiplication , we get */

 \implies 8(1-9y) = 5(19-3y)

 \implies 8 - 72y = 95 - 15y

/* Add bothsides by 15y , we get */

 \implies 8 - 72y + 15y = 95 - 15y + 15y

 \implies 8 - 57y  = 95

/* Subtract bothsides by 8 , we get */

 \implies 8 - 57y - 8 = 95 - 8

 \implies  - 57y = 87

 \implies  y = \frac{87}{-57}

Therefore.,

 \red { Value \: of \: y } \green {= -\frac{87}{57}}
