The value of 3n-(2+n) is 6 for n=4. This is obtained by applying simple algebraic operations such as adding like terms to the given expression.
Expression:
An expression consists of coefficients, variables, and constants.
How to simplify an expression?
- Expand the expression according to the operators in the expression like brackets.
- Use distributive law for expanding
- Add the terms with the same variable which are called like terms
- Simplify the obtained sum.
Calculating for the value of n:
Given expression is 3n - (2+n) and it has a solution 6 for a value of n.
So, it can be written as 3n - (2+n) = 6
Expanding the obtained equation:
3n-2-n=6
Adding like terms
(3n - n) - 2 = 6
2n=6+2
2n=8
⇒ n=4
Therefore, for n=4 the value of the given expression is equal to 6.
