Пошаговое объяснение

x + 1 1/4 = -4 11/12

x = -4 11/12 - 1 1/4

x = -4 11/12 - 1 3/12

x = -5 14/12

x = -6 1/6

========

x : (-5/8) = 24/25

x = 24/25 *(-5/8)

x = -3/5

=============

4/12 :(-x) = -4

-x = 4/12 : (-4)

-x = 4/12 *(-1/4)

-x = -1/12

x = 1/12

==========

-4,8x + 5x = -0,04

0,2x = -0,04

x = -0,04:0,2

x = -0,2

============

8x +4(2x-1) = 8x + 8x - 4 = 16x - 4

-6(5x + 1) - 20x = -30x - 6 - 20x = -50x - 6

-a -(-a - 4) = -a + a + 4 = 4

9x - 3(3x - 1) + 10 = 9x - 9x + 3 + 10 = 13

4(5x - 3) - 15x + 3 = 20x - 12 - 15x + 3 = 5x - 9

-7a + 8(a - 2) = -7a + 8a - 16 = a - 16

3(3a - 5) - 3(4a - 6) = 9a - 15 - 12a + 18 = -3a + 3
