Answer:

n=5

Step-by-step explanation:

First put the like numbers on the same sides. The n on one and the numbers on the other.

7n-4n=17-2

3n=15

n=5

Answer: n=5

Step-by-step explanation:

7n + 2 = 4n + 17, so first we subtract 2 from both sides.

      -2           -2

Now the equation should look like this:

7n= 4n + 15

Now since 4n is smaller than 7n we are going to subtract 4n from both sides.

7n = 4n  +15

-4n  -4n  

Now the equation should look like this:

3n = 15

All that is left to do is divide by 3 on both sides.

3n/3 = 15/3

n = 5
