Step by step
The question
Question: simplify −(x − 6).
Simplify means: write it shorter, with the same value.
−(x − 6)
1 Open the brackets
A minus in front of a bracket changes the sign of every part inside.
−( + ) → −, −( − ) → +
Now we have −x + 6.
= −x + 6
2 Check
Let's check.
We pick a number for each letter: x = 2.
We put it into the start.
Start: −(2 − 6) = −(−4) = 4
Now into our answer.
Answer: −2 + 6 = 4
Both give 4.
Same value, so −x + 6 is right!
Both give 4
Let's look back.
First: open the brackets.
Last: check.
Answer
= −x + 6
