Answer:
y=t/(12dt+19)
Step-by-step explanation:
This question want us to make y the subject of formula...it involves a step by step process
Back to the question
12ytd=-19y+t
Let's start solving by asking how can we make y the subject of formula from this equation...you have to be a fast thinker
Let's continue with the solution
12ytd=-19y+t
Add 19y to both sides
12ydt+19y=t
Then factorise only from the left side and y is common to the two figures
y(12dt+19)=t
Divide both sides by (12dt+19)
y=t/(12dt+19)
Therefore the final answer is y=t/(12dt+19)
