Simplify the expression: 7n - 6n + 7 ____

Identify Like Terms: Identify like terms in the expression 7n - 6n + 7. Like terms are terms that contain the same variable raised to the same power. Here, 7n and -6n are like terms, while 7 is a constant and does not have a like term in the expression.Combine Like Terms: Combine the like terms 7n and -6n. To combine like terms, we add or subtract their coefficients. In this case, we subtract the coefficients of n: 7n - 6n = (7 - 6)n = 1n = nRewrite Expression: Rewrite the expression with the combined like terms. Now that we have combined the like terms, we can rewrite the expression as: n + 7

Q. Simplify the expression:

\newline

7n - 6n + 7

Identify Like Terms: Identify like terms in the expression $7n - 6n + 7$ . Like terms are terms that contain the same variable raised to the same power. Here, $7n$ and $-6n$ are like terms, while $7$ is a constant and does not have a like term in the expression.
Combine Like Terms: Combine the like terms $7n$ and $-6n$ . To combine like terms, we add or subtract their coefficients. In this case, we subtract the coefficients of $n$ : $7n - 6n = (7 - 6)n$ $= 1n$ $= n$
Rewrite Expression: Rewrite the expression with the combined like terms. $\newline$ Now that we have combined the like terms, we can rewrite the expression as: $\newline$ $n + 7$
