The mistake made by Enduro is that he is supposed to divide both sides by -4 instead of adding 4 to each sides
<h3>What are inequalities?</h3>
Inequalities are expressions that have unequal values, when compared
<h3>How to determine Enduro's mistake?</h3>
The inequality is given as
-4x > 120
When 4 is added to both sides, the inequality becomes
4 - 4x > 120 + 4
The above is not the solution to the inequality.
The solution is as follows:
We have:
-4x > 120
Divide both sides inequality by -4
x < -30
Hence, the mistake made by Enduro is that he is supposed to divide both sides by -4 instead of adding 4 to each sides

If you don't want to mess with adding and subtracting obscure fractions, you can let your calculator do it.
_____
I find it convenient to add the integer parts separately from the fractional part. Usually, only a slight adjustment is needed at the end.
Integer parts:
... 170 +25 -10 -3 = 182
Fractional parts:
... 2/3 +5/12 -1/4 -1/2 = (8 +5 -3 -6)/12 = 4/12 = 1/3 (added to the above)
Weight after 2 weeks of practice: 182 1/3 lbs.
