Пошаговое объяснение:
А)
13 - 100х = 0
100х = 13 - 0
100х = 13
х = 13/100 или 0,13
Б)
7х - 4 = х - 16
7х - х = -16 + 4
6х = -12
х = -12 : 6
х = -2
В)
13 - 5х = 8 - 2х
-5х + 2х = 8 - 13
-3х = - 5
х = -5 : (-3)
х = 5/3
х = 1. 2/3
Г)
4у + 15 = 6у + 17
4у - 6у = 17 - 15
-2у = 2
у = 2 : (-2)
у = -1
Д)
5х + (3х - 7) = 9
5х + 3х - 7 = 9
5х + 3х = 9 + 7
8х = 16
х = 16 : 8
х = 2
Е)
3у - (5 - у) = 11
3у - 5 + у = 11
3у + у = 11 + 5
4у = 16
у = 16 : 4
у = 4
Ж)
13 - (5х + 11) = 6х
13 - 5х - 11 = 6х
-5х - 6х = -13 + 11
-11х = -2
х = -2 : (-11)
х = 2/11
З)
(7х + 1) - (6х + 3) = 5
7х + 1 - 6х - 3 = 5
7х - 6х = 5 - 1 + 4
х = 8
И)
(5х + 2) - (4х + 7) = 8
5х + 2 - 4х - 7 = 8
5х - 4х = 8 - 2 + 7
х = 13
