Final answer:
To solve 6(e−1)−3(e−2)=−15, you distribute and combine like terms, resulting in 3e = −15, which simplifies to e = 5, matching option C.
Step-by-step explanation:
To simplify the equation 6(e−1)−3(e−2)=−15, let's distribute the numbers outside the parentheses and then combine like terms:
- 6(e−1) becomes 6e − 6.
- −3(e−2) becomes −3e + 6.
- Combining these we get 6e − 3e − 6 + 6.
- Which simplifies to 3e − 6 + 6.
- Since −6 and +6 cancel each other out, we are left with 3e = −15.
- Divide both sides by 3 to isolate e.
- e = −15 / 3.
- Therefore, e = −5.
So the correct answer is e = 5, which corresponds to option C.
