## anonymous 4 years ago HELP PLEASE. What is the value of x? 3√9+x=15

1. anonymous

2. anonymous

3. anonymous

3

4. anonymous

perfect!

5. anonymous

$3\cdot3+x=15$

6. anonymous

what is 3 times 3?

7. anonymous

9

8. anonymous

ok so we now have $9+x=15$ how do we get the 9 to the other side of the equal sign?

9. anonymous

make a guess

10. anonymous

i really don't know :/ i have been out of math for 3 years now. :(

11. anonymous

no problem

12. anonymous

we would subtract 9 from both sides to get x by itself so $\cancel{9-9}+x=15-9$

13. anonymous

Yes! Good job!
