∣3x−5∣=4
To solve this problem, we'll follow these steps:
- Step 1: Consider the positive scenario: 3x−5=4
- Step 2: Consider the negative scenario: 3x−5=−4
- Step 3: Solve each equation separately
- Step 4: Identify the correct answer from the given choices
Let's work through each step:
Step 1: Solve 3x−5=4.
Add 5 to both sides:
3x−5+5=4+5
So, 3x=9.
Divide both sides by 3:
x=39, thus x=3.
Step 2: Solve 3x−5=−4.
Add 5 to both sides:
3x−5+5=−4+5
So, 3x=1.
Divide both sides by 3:
x=31.
Step 3: We have two solutions for x, namely x=3 and x=31.
Step 4: Comparing this with the given choices, the correct answer is "Answers b + c":
- x=3 corresponds to choice b.
- x=31 corresponds to choice c.
Therefore, the solution to the problem is Answers b + c.
