Решите уравнения: 3,4 * (0,4 х+0,2) + 1,52=8,32

44,62: (7,8+0,5 х) + 26,51=31,11

3,4 * (0,4 х+0,2) + 1,52=8,32

3,4*0,4 х+3,4*0,2+1,52=8,32

1,36x + 0.68 + 1.52 = 8.321.36x = 8.32 - 0.68-1.52

1.36x = 6.12

x = 6.12 : 1.36

x = 4.5

2) 44,62: (7,8+0,5 х) + 26,51=31,11

44.62: (7,8+0,5x) = 31.11-26.51

44.62 : (7.8+0.5x) = 4.6

7.8+0.5x = 44.62 : 4.6

7.8 + 0.5x = 9.7

0.5x = 9.7 - 7.8

0.5x = 1.9

x = 1.9 : 0.5

x = 3.8
