To simplify the expression \( 14y - 6 + 3(4y + 7) \), follow these steps in order:
-
Distribute the 3 across the expression in parentheses:
- This means calculating \( 3 \times 4y \) and \( 3 \times 7 \).
- Result: \( 3(4y + 7) = 12y + 21 \).
-
Rewrite the expression with the distributed terms included:
- This updates the beginning expression: \( 14y - 6 + 12y + 21 \).
-
Combine like terms:
- Combine the terms involving \( y \): \( 14y + 12y = 26y \).
- Combine the constant terms: \( -6 + 21 = 15 \).
-
Write the simplified expression:
- Final result: \( 26y + 15 \).
In order, the steps are:
- Distribute the 3 across the expression in parentheses.
- Rewrite the expression with the distributed terms included.
- Combine like terms.
- Write the simplified expression.
