Question

What is the value of x in the equation 8x – 2y = 48, when y = 4?

Answer 1

Hey there!

So, if
`y=(4)`, this would mean that we would do
`(2 \ * \ 4)` and from this, we would get 8.

We will then need to find what is
`(x)`.


`(x) = 7`


`8*7` =
`\boxed{56}`

So, the equation would really look like . . .


`\left[\begin{array}{ccc} 8*(7)-2*4 = 48 \\ \\ x=\boxed{7}\end{array}\right]`

Hope this helps.
