a) 7,2 (6,2 - x) = 2,2; 6)-5+ (a25) = -4; 16 = 58 г) (х+3) 17 = -20; д) (106) + 23,5 = -40,4; e) (m+-

а) 7.2 - (6.2 - x) = 2.2

6.2 - x = 7.2 - 2.2

6.2 - x = 5

-x = 5 - 6.2

-x = -1.2

x = 1.2

б) -5 + (a - 25) = -4

a - 25 = -4 + 5

a - 25 = 1

a = 1 + 25

a = 26

в) \(\frac{5}{16}\) - (\(\frac{3}{16}\) - x) = \(\frac{5}{8}\)

\(\frac{5}{16}\) - \(\frac{3}{16}\) + x = \(\frac{5}{8}\)

\(\frac{2}{16}\) + x = \(\frac{5}{8}\)

x = \(\frac{5}{8}\) - \(\frac{1}{8}\)

x = \(\frac{4}{8}\)

x = \(\frac{1}{2}\)

г) (x + 3) - 17 = -20

x + 3 = -20 + 17

x + 3 = -3

x = -3 - 3

x = -6

д) -(10 - b) + 23.5 = -40.4

-10 + b = -40.4 - 23.5

-10 + b = -63.9

b = -63.9 + 10

b = -53.9

e) \(|m + \frac{2}{15}|\) - \(\frac{2}{15}\) = 0.8

\(|m + \frac{2}{15}|\) = 0.8 + \(\frac{2}{15}\)

\(|m + \frac{2}{15}|\) = \(\frac{8}{10}\) + \(\frac{2}{15}\)

\(|m + \frac{2}{15}|\) = \(\frac{4}{5}\) + \(\frac{2}{15}\)

\(|m + \frac{2}{15}|\) = \(\frac{12}{15}\) + \(\frac{2}{15}\)

\(|m + \frac{2}{15}|\) = \(\frac{14}{15}\)

m + \(\frac{2}{15}\) = \(\frac{14}{15}\) или m + \(\frac{2}{15}\) = -\(\frac{14}{15}\)

m = \(\frac{14}{15}\) - \(\frac{2}{15}\) или m = -\(\frac{14}{15}\) - \(\frac{2}{15}\)

m = \(\frac{12}{15}\) или m = -\(\frac{16}{15}\)

m = \(\frac{4}{5}\) или m = -1\(\frac{1}{15}\)
