a)
13x - 2 - 15 - 6x = -3x - 3
7x - 17 = -3x - 3
10x = 14
x = 1.4
б)
12 - 4x + 10 = 44 + 4x + 6 - 6x
22 - 4x = 44 - 2x
-2x = 22 - 44
x = -11
в)
1.6x + 1.6 - x + 1.8 = 0.2x + 1.7 - 0.7
0.6x + 3.4 = 0.2x + 1
0.4x = -2.4
x = -6
г)
0.5x + 1.7 + 4.5 + 0.3x = 4.5 - 0.3x + 15 - 0.1x + 10.5 + 1.11
0.8x + 6.2 = 30 - 0.4x
1.2x = 23.8
x = 19.83
