Пошаговое объяснение:
-6x + 8 = 15x - 13
15x + 6x = 8+13
21x = 21
x = 21:21
x = 1
=============
2(x - 3) = 5 + 3(2x - 1)
2x - 6 = 5 + 6x - 3
2x - 6 = 2 + 6x
6x - 2x = -6 - 2
4x = -8
x = -8 : 4
x = -2
===============
3,7x - 0,8 = 4,2 + 1,2x
3,7x - 1,2x = 4,2 + 0,8
2,5x = 5
x = 5 : 2,5
x = 2
(x + 0,5)/2 = (0,4 - x)/4
4*(x + 0,5) = 2*(0,4 - x)
4x + 2 = 0,8 - 2x
4x + 2x = 0,8 - 2
6x = -1,2
x = -1,2 : 6
x = -0,2
