<span>If you would like to know in which step did the student first make an error, you can find this using the following steps:

y = 4 - 2z
4y = 2 - 4z

-4y = -16 + 8z ... Step 2
</span><span>4y = 2 - 4z</span><span>
________________
0 = -16 + 8z + 2 - 4z</span>

<span>16 - 2 = 4z</span>

<span>14 = 4z</span>

<span>z = 14/4 = 7/2</span>

<span>
The correct result would be: Student made an error in Step 2.</span>
