∣x−3∣=4
To solve the equation ∣x−3∣=4, follow these steps:
- Step 1: Understand that ∣x−3∣=4 means x−3 can be either 4 or -4.
- Step 2: Set up two separate equations:
- Equation 1: x−3=4
- Equation 2: x−3=−4
- Step 3: Solve each equation for x.
Let's solve Equation 1:
x−3=4
Add 3 to both sides:
x=4+3
x=7
Now, solve Equation 2:
x−3=−4
Add 3 to both sides:
x=−4+3
x=−1
Therefore, the solutions to the equation ∣x−3∣=4 are x=7 and x=−1.
Checking the given choices, the correct answer is:
x=−1, x=7, which matches choice 1.
x=−1 , x=7
