What is the value of n when 7n – 18 = 5n + 6?

n=12

Step-by-step explanation:

7n-18 =5n+6

+18 to both sides

7n=5n+24

-5n from both sides

2n=24

divide by 2

n=12

n=13

Step-by-step explanation:

7n-18=5n+6   move variables to 1 side

-5           -5    (in this case subtract 5 on both sides of the equal sign)

2n-18=  6        now you want to get the variable alone

   +18   +18     (in this case add 18 on both sides of the equal sign)

2n=26             now you want to get the variable (N) by itself

/2    /2            ( so divide 2 on both sides of the equal sign )

n=13
