Not rly sure but my best :)
Based on the algebraic rules for subtracting negative numbers,
when you subtract a negative number, the two negative signs cancel out and instead becomes an addition sign.
For example:
a - -b = a+b
-a - -b = -a + b
Therefore, following this rule,
the equation -51-(-60)
will change the -(-60) into a +60, so
-51 + 60
60-51 = 9
75.89 + 0.12x = 27.41 + 0.36x
75.89 - 27.41 = 0.24x
48.48 = 0.24x
x = 48.48 / 0.24
x = 202
