Question

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

Answer 1

Answer:

$x=\frac{7}{2}=3.5$

Step-by-step 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:

$\frac{2x}{2}=\frac{7}{2}$

The left cancels. So:

$x=\frac{7}{2}=3.5$

So, our answer is 7/2 or 3.5.

And we're done!

Answer 2

Answer:

x=7/2

Step-by-step explanation:

First bring the 8 to the other side of the equation

2x=15-8

Then solve for x

2x=7

x=7/2
