Question

Below are the steps to solve an equation:

Step 1: |x – 5| + 2 = 5
Step 2: |x – 5| = 5 – 2
Step 3: |x – 5| = 3

Which of the following is a correct next step to solve the equation?

x + 5 = -3

-x – 5 = 3

x - 5 = -3

x + 5 = 3

Answer 1

he table shows the solution to the equation |2x – 3| - 1 = 2:


Step 1 |2x – 3| = 2 + 1
Step 2 |2x – 3| = 3
Step 3 2x – 3 = 3 or 2x + 3 = 3
Step 4 2x = 6 or 2x = 0
Step 5 x = 3 or x = 0


Which is the first incorrect step?
Step 1

Step 3

Step 5

Solution is correct
