## mathtard 3 years ago $\sqrt{5x+6}=15$ please help solve!

1. satellite73

1) square 2) subtract 6 3) divide by 5

2. mathematicalpro

$5x+6=225$ $5x=219$ $x=219/5$

3. mathtard

I see where you got 219 but it says incorrect for the answer. When I did the steps Satellite 73 said I got 219 as well. Maybe I am missing something?

4. satellite73

it is not 219 it is $\frac{219}{5}$ that is why it said "incorrect"

5. mathtard

I know. I entered 219/5 It still said incorrect.
