To determine if the two expressions \(2(x-1)+18\) and \(6(x+3)-4x-6\) are equivalent, we need to simplify both expressions and then compare them. Let's start by simplifying each expression step by step.
Simplifying the Left Expression
- Write down the expression:
\[ 2(x - 1) + 18 \] - Distribute \(2\) into the parentheses:
\[ 2 \cdot x - 2 \cdot 1 + 18 = 2x - 2 + 18 \] - Combine like terms:
\[ 2x + 16 \]
Simplifying the Right Expression
- Write down the expression:
\[ 6(x + 3) - 4x - 6 \] - Distribute \(6\) into the parentheses:
\[ 6 \cdot x + 6 \cdot 3 - 4x - 6 = 6x + 18 - 4x - 6 \] - Combine like terms:
- Combine \(6x - 4x\) to get \(2x\).
- Combine \(18 - 6\) to get \(12\).
So:
\[ 2x + 12 \]
Comparing the Two Expressions
Now we can compare the simplified forms of both expressions:
- Left Expression: \(2x + 16\)
- Right Expression: \(2x + 12\)
Since \(2x + 16\) is not equal to \(2x + 12\), we conclude that the two expressions are not equivalent.
Conclusion
The final result shows: \[ 2(x-1) + 18 \neq 6(x+3) - 4x - 6 \] Thus, the answer is no, the two expressions are not equivalent.
