Answer:

He or she did not properly use the subtraction property of equality. On the right side in the second step of the equation, he or she added 3.8. The correct method to solve for x is by subtracting 3.8 on both sides. Therefore, the answer should be x = -1.5 because 2.3 - 3.8 = -1.5.

The description is very simple: Incorrectly solved.

More specifically at step 2 the subtraction of 3.8 should have been on both sides.


</p><p>x+3.8=2.3 \\</p><p>x+3.8-3.8=2.3-3.8 \\</p><p>\boxed{x=-1.5}</p><p>

Hope this helps.
