Question

23X - 22=19X + 6
12X - 16= -21 + 10X
1,9X - 3,6=X - 10,8
Obrigado(a)!​

Answer 1

Resposta:

• 23x - 22 = 19x + 6

23x + 19x = 22 - 6

42x = 16

X = 16/42

• 12x - 16 = -21 + 10x

12x + 10x = -21 - 16

22x = -37

X = -37/22

• 1,9x - 3,6 = x - 10,8

1,9x + x = 3,6 + 10,8

2,9x = 14,4

X = 14,4/2,9

Bons estudos, amigo(a)!
