6. anonymous

8. Candy13106

9. anonymous

no

10. Candy13106

oh

11. Candy13106

can u tell me how u got that

12. anonymous

hold on

13. zpupster

8.67

14. mathstudent55

n is being multiplied by 2 and then 7/3 is being subtracted. First, you must add 7/3 to both sides.

my brother was helping me and explaining it he got 8.67... and it made sense but everyone is saying something else

16. Candy13106

8.6 is right because you do \[26 \div 3\]

15+7/3 is 17.3 right?

22. mathstudent55

23. mathstudent55

Now that we have 2n, and we want n, we divide both sides by 2. Dividing by 2 is the same as multiplying by 1/2

my answer doesnt have a fraction

26. zpupster

i would like to offer an alternative mult whole equation by 3 3(2n-7/3=15) and you end up with 6n - 7 =45 add 7 to both and then divide both by 6 n=52/6 n=8.67

27. zpupster

or 8 2/3 = 8.67
