resolva as equações

a) 16x - 1 =4x + 9

b) -40=-5x

C) 15=-3x

D) 2x/5=-18

E) 5x+6x-16=3x+2x-4​

Answer 1

Explicação passo-a-passo:

a) 16x -4x = 9 +1

12x = 10

x = 10/12

x= 5/6

b) 5x = 40

x= 40/5

x= +8

c) 15/-3= x

x= - 5

d) 2x = -18 . 5

2x = - 90

x= -90/2

x= - 45

e) 11x -16 = 5x -4

11x - 5x = -4 +16

6x = 12

x= 12/6

x= 2
