Soluções para a tarefa
Respondido por
2
A) 2X - 8 = 8
2x = 8 + 8
2x = 16
x = 16/2
x = 8
B) 3X + 1 = 19
3x = 19 - 1
3x = 18
x = 18/3
x = 6
C) 9X + 5 = 50 + X - 5
9x - x = 50 - 5 - 5
8x = 50 - 10
8x = 40
x = 40/8
x = 5
D) 7x + 1 - 5x = 9
7x - 5x = 9 -1
2x = 8
x = 8/2
x = 4
E) 20x - 13 = 20 - 9X
20x + 9x = 20 + 13
29x = 33
x = 33/29
F) 13X - 27 = -23 + 9X
13x - 9x = -23 - 27
4x = - 50
x = -50/4
G) 6X - 32 = -20
6x = -20 + 32
6x = 12
x = 12/6
x = 2
H) 6X + 5 = 2 + 5X
6x - 5x = 2 - 5
x = - 3
