Answer:
a = f (b) = - 13 ⁷/4 b
Step-by-step explanation:
Since we have given that
4a + 7b = 52
We need to write a formula for f (b) in terms of b So , it becomes :
4a = 52 - ⁷b
a = -52- ⁷b ÷ 4
a = -52÷4 - ⁷b ÷ 4 -
a = 13 = ⁷b ÷ 4
Hence our required formula becomes :
a = f (b) = - 13 =⁷b ÷ 4
The ⁷b ÷ 4 means ⁷b over 4 :)
