Question

He table shows the solution to the equation |2x − 5| − 2 = 3:

Step 1 |2x − 5| = 3 + 2
Step 2 |2x − 5| = 5
Step 3 2x − 5 = 5 or 2x − 5 = −5
Step 4 2x = 10 or 2x = 0
Step 5 x = 5 or x = 0


Which is the first incorrect step?
Step 3
Step 4
Step 5
Solution is correct

Answer 1

The solution is completely correct, as putting 5 or 0 in the formula again will make it true.


`|2(0)-5|=5`

`|-5|=5`

`5=5`


`|2(5)-5|=5`

`|10-5|=5`

`5=5`
