44.

1) 0.9x - 0.6x + 1.8 = 0.4x - 2.6

0.9x - 0.6x - 0.4x = -1.8 - 2.6

-0.1x = -4.4

x = 44

2) -1.2x + 0.4 + 6.4x - 2.4 = 5 - 3.8x + 4

-1.2x + 6.4x +3.8x = 5 + 4 - 0.4 + 2.4

9x = 11

x = 11/9 или 1.2

3) 0.32 - 2.4y + 0.4 = 0.2 - 2.5y

2.5y - 2.4y = 0.2 - 0.32 - 0.4

0.1y = -0.52

y = -5.2

46.

1)-216x - 36 = 36 - 18x

-216x + 18x = 36 + 36

-198x = 72

x = -0.36

2) 9.6x - 6.4 = -28.8 + 9.6x

9.6x - 9.6x = -28.8 +6.4

x = -22.4
