To solve the equation 7n - 7 = 42, we need to isolate the variable n.
First, we can start by adding 7 to both sides of the equation to eliminate the -7 on the left side:
7n - 7 + 7 = 42 + 7
Simplifying, we get:
7n = 49
Next, to solve for n, we divide both sides of the equation by 7:
7n/7 = 49/7
Simplifying, we have:
n = 7
Therefore, the solution to the equation 7n - 7 = 42 is n = 7.
7n - 7 = 42
