To simplify the expression \( 14y - 6 + 3(4y + 7) \), follow these steps in order:
-
Start with the given expression: \[ 14y - 6 + 3(4y + 7) \]
-
Distribute \(3\) in the term \(3(4y + 7)\): \[ 14y - 6 + 3 \cdot 4y + 3 \cdot 7 \] This simplifies to: \[ 14y - 6 + 12y + 21 \]
-
Combine like terms (combine \(14y\) and \(12y\), and combine \(-6\) and \(21\)):
- Combine \(14y\) and \(12y\): \(14y + 12y = 26y\)
- Combine \(-6\) and \(21\): \(-6 + 21 = 15\)
This results in: \[ 26y + 15 \]
-
Final simplified expression: \[ 26y + 15 \]
So, the simplification steps in order are as follows:
- Start with \( 14y - 6 + 3(4y + 7) \)
- Distribute \(3\): \( 14y - 6 + 12y + 21 \)
- Combine like terms: \( 26y + 15 \)
- Final result: \( 26y + 15 \)
