Question

The table shows the solution to the equation |2x - 4| - 3 = 3:

Step 1 |2x - 4| = -3 + 3
Step 2 |2x - 4| = 0
Step 3 2x - 4 = 0
Step 4 2x = 4
Step 5 x = 2


Which is the first incorrect step?

Step 1

Step 2

Step 3

Solution is correct

Answer 1

|2x-4|-3=3
|2x-4|=3+3 (here -3 is incorrect it should not be negative
|2x-4|=6

Answer 2

on removing mod
\[2x-4=\pm6\]

Answer 3

2x-4=6 and 2x-4=-6
2x=4+6=10 2x=-6+4=-2
x=5 x=-1
x=5 or x=-1

Answer 4

step 2 was wrong?

Answer 5

we can see step 1 is incorrect

Answer 8

The table below shows two equations:

Equation 1 |2x - 3| + 5 = 4
Equation 2 |5x + 3| - 10 = 3


Which statement is true about the solution to the two equations?

Equation 1 and equation 2 have no solutions.

Equation 1 has no solution and equation 2 has solutions x = 2, -3.2.

The solutions to equation 1 are x = 1, 2 and equation 2 has no solution.

The solutions to equation 1 are x = 1, 2 and equation 2 has solutions x = 2, -3.2.
