Step-by-step explanation:

Answer:
Heyya !
Here's how to do it:-
First write down what's given:-
y -7.2 = 8
Next, we do like this:-
y = 8+ 7.2
We transferred 7.2 to the other side of the ' = ' sign.
When we do so, the sign of the number changes
Here 7.2 was negative first but when we transferred it to the other side, its sign changed to positive.
So,
y = 8 + 7.2
Now, just add it!
8 + 7.2 equals 15.2
<h2>So, the value of y is 15.2 </h2><h2 /><h3>I hope the explanation was clear.</h3><h3>If you still have doubts, let me know in the comments !</h3>
