5(y–3.8)=4.7(y–4) help help
melomori [17]

Answer:

<h2>y = 2/3 or 0.667</h2>

Step-by-step explanation:

5(y–3.8)=4.7(y–4)

Expand the terms in the bracket

That's

5y - 19 = 4.7y - 18.8

Group like terms

5y - 4.7y = 19 - 18.8

0.3y = 0.2

Divide both sides by 0.3

We have the final answer as

<h3>y = 2/3 or 0.667</h3>

Hope this helps you
