Question

9a=(12a+3b)/4 solve for a plz.

Answer 1

a = b/8

Explanation:

The question is given as:

`9a = ((12a+3b))/(4)\\`

Multiplying both sides of above equation by '4',

`4*9a = (12a+3b)/(4) *4\\36a = 12a+3b\\36a-12a = 3b\\24a = 3b\\`

Dividing both sides of above equation by '3',

`(24)/(3) = b\\8a = b\\a = (b)/(8)`
