Answer:
a = k/(4 + 9b)
Step-by-step explanation:
Here, we want to make a the formula subject
We have this as;
k = a(4 + 9b)
a = k/(4 + 9b)
The expression for a fom the give expression is a = k/(4 + 9b)
Subject of formula
Given the following equation
K = 4a + 9ab
Factor out the GCF
K = a(4 + 9b)
Divide both sides by 4 + 9b
k/4+9b = a(4 + 9b)/4+9b
k/(4 + 9b) = a
Hence the expression for a fom the give expression is a = k/(4 + 9b)
