Questions: Simplify the expression.
2 r - 6 r + 7 + r
Transcript text: Simplify the expression.
\[
2 r-6 r+7+r
\]
Solution
Solution Steps
To simplify the expression \(2r - 6r + 7 + r\), we need to combine like terms. The terms involving \(r\) are \(2r\), \(-6r\), and \(r\). The constant term is \(7\). We will sum the coefficients of \(r\) and then add the constant term.
Step 1: Combine Like Terms
We start with the expression:
\[
2r - 6r + 7 + r
\]
We identify the like terms involving \(r\): \(2r\), \(-6r\), and \(r\).
Step 2: Calculate the Coefficients
We sum the coefficients of \(r\):
\[
2 - 6 + 1 = -3
\]
Step 3: Write the Simplified Expression
Now, we can express the simplified form of the original expression:
\[
-3r + 7
\]
