Solve this problem.
7n - 7 = 42
n =Blank Space __________
n = 7
To solve the equation 7n - 7 = 42 and find the value of n, you need to isolate the variable n on one side of the equation. Here's the step-by-step process:
1. Start with the equation: 7n - 7 = 42.
2. Add 7 to both sides of the equation to get rid of the -7: 7n - 7 + 7 = 42 + 7.
This simplifies to: 7n = 49.
3. now we have 7n = 49, to solve for n, we need to isolate it, divide both sides of the equation by 7: 7n/7 = 49/7.
This simplifies to: n = 7.
So, the value of n that satisfies the equation 7n - 7 = 42 is n = 7.
To solve the equation 7n - 7 = 42, you need to isolate the variable n. Here are the steps:
Step 1: Add 7 to both sides of the equation to eliminate the constant term on the left side:
(7n - 7) + 7 = 42 + 7
Simplifying, we get:
7n = 49
Step 2: Divide both sides of the equation by 7 to isolate n:
7n/7 = 49/7
Simplifying, we get:
n = 7
Therefore, the solution to the equation 7n - 7 = 42 is n = 7.
