Answer:

Hi there, I believe the answer to this equation is: 2.8

Step-by-step explanation:

Subtract 7 on both sides so

5n+7=21-7

you are left with 5n=14 you need to get n by itself so divide 5 on both sides.

5n/5 = 14/5

n=2.8

Hope this is correct :)

Have a great day

Is (6,-10) a solution of y=3x-8

Vitek1552 [10]

You can easily test this if you know that (6, -10) corresponds to (X, Y). Knowing this, you can:

X = 6
Y = -10

you put this into your equation:

-10 = 3*6 - 8

calculate it:

-10 = 18 - 8
-10 = 10
This is not true of course, -10 is not equal to 10. Therefore, (6, -10) is not a solution of y = 3x-8 :)
