Answer 1

1)-1/20  +1/30= -1/60    60 -общий знаменатель   От модуля большего отнимаем модуль меньшего и ставим знак большего модуля

Answer 2

To solve the equation -1/20 + 1/30 = x, where x is the unknown value, we can use the following steps:

1. Find a common denominator for the two fractions. The smallest number that both 20 and 30 divide into is 60, so we can rewrite the equation as:

   -3/60 + 2/60 = x

2. Combine the numerators of the fractions:

   -1/60 = x

Therefore, the solution to the equation -1/20 + 1/30 = x is x = -1/60.
