Answer:
b=-20
Step-by-step explanation:
We will have to solve this question based on how the question is given
So let's solve the given question
2=7+b/4
To start by finding the LCM for the right side and the LCM is 4
2=28+b/4
Let's cross multiply
2×4=28+b
8=28+b
Let's make b the subject of formula by substrating 28 from both sides
-20=b
Therefore the final answer is b=-20
