What is the first step in the problem below? 1+n/7=3

A. Do the reciprocal of 1/7
B. Divide both sides by 7
C. Multiply both sides by 7 for the inverse
D. Subtract 1 on both sides for the inverse

C.

Step-by-step explanation:

I'm assuming that the equation is (1+n) / 7 = 3, where 1+n is the numerator and 7 is the denominator.

In this case, to isolate for n, you have to multiply both sides by 7.

then you get 1+n = 3/7, and then you can get n = 3/7 - 1

examine the two-step equation.
