Question

2x+8=15 help fast please and show work!

Answer 1

x=7/2

Explanation:

First bring the 8 to the other side of the equation

2x=15-8

Then solve for x

2x=7

x=7/2

Answer 2

`x=(7)/(2)=3.5`

Explanation:

So we have the equation:

`2x+8=15`

To solve for x, we need to isolate it. Let's subtract 8 from both sides:

`(2x+8)-8=(15)-8`

The left cancels. Subtract on the right:

`2x=7`

Now, let's divide both sides by 2:

`(2x)/(2)=(7)/(2)`

The left cancels. So:

`x=(7)/(2)=3.5`

So, our answer is 7/2 or 3.5.

And we're done!
