Question

Rearrange the equation so m is the independent variable. 7m + 2 = 7n − 5 , n =

Answer 1

We have that 7m + 2 = 7n - 5

If we want to get n, you can use operations in both sides of the equation to make n the independent variable.

First, from 7m + 2 = 7n - 5, we can sum to both sides 5

7m + 2 + 5 = 7n - 5 + 5

7m + 7 = 7n

Now, we can devide both sides by 7:

(7m+7) /7 = 7n/7

7m/7 + 7/7 = n

m + 1 = n

Answer 2

n=m+1

Explanation:

7m+2=7n-5

add 5 to each side

7m+7=7n or 7n=7(m+1)

divide both sides by 7

n=m+1
