Question

When x is 15 solve for y.3x - 8y = 5

Answer 1

Given

The equation:

3x-8y=5.

To find the value of y when x is 15.

Step-by-step explanation:

It is given that,

`3x-8y=5`

Since x=15.

Then,

`\begin{gathered} 3(15)-8y=5 \\ 45-8y=5 \\ 8y=45-5 \\ 8y=40 \\ y=(40)/(8) \\ y=5 \end{gathered}`

Hence, the value of y is 5.
