4n − 5 = 3n + 2
I know its 6 but i don't know how to solve it.!!!!!!!!@@@23q9
I would subtract 3n from each side, and add 5 to each side.
I am wondering how you "know" it is 6 if you don't know how to solve it. In fact, it is not six.
The answer is not 6.
4n − 5 = 3n + 2
Subtract 3n from both sides.
n - 5 = 2
Add 5 to both sides.
n = 7
Proof:
4(7) - 5 = 3(7) + 2
28 - 5 = 21 + 2
23 = 23
To solve the equation 4n - 5 = 3n + 2, you need to isolate the variable n on one side of the equation. Here's how you can do it step by step:
1. Start with the equation: 4n - 5 = 3n + 2.
2. The goal is to get all terms with n on one side and constants on the other side. To achieve this, you can subtract 3n from both sides of the equation. This cancels out the 3n on the right side:
4n - 3n - 5 = 3n - 3n + 2.
Simplifying the left side gives:
n - 5 = 2.
3. Next, you want to isolate n by getting rid of the constant term -5. To do this, you can add 5 to both sides of the equation:
n - 5 + 5 = 2 + 5.
After simplifying, you get:
n = 7.
Therefore, the solution to the equation 4n - 5 = 3n + 2 is n = 7.
