What is the value of y? PLEASE EXPLAIN<br> 8.5 = y/3 &lt;------ Fraction
NISA [10]

Answer:

y=25.5

Step-by-step explanation:

To find y, you need to get it by itself. Ask yourself, what is being done to y, then to undo that, do the opposite. For example, if 3 was added to y, you would need to subtract 3 to cancel out the 3. In this case, what is being done to y? It's being divided by 3. So, you multiply by 3 to cancel that out. Whatever you do to one side of an equation, you also have to do to the other. So,

8.5=\frac{y}{3}   Multiply both sides by 3

3(8.5) = 3(\frac{y}{3})  multiply on the left side, and on the right side the 3s cancel out

25.5=y
