Question

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

Answer 1

n=13

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

Answer 2

n=12

Explanation:

7n-18 =5n+6

+18 to both sides

7n=5n+24

-5n from both sides

2n=24

divide by 2

n=12
