Question

Resolva As Seguintes Equações :
A)2x=16
B)3x=-21
C)36x=0
D)14x=56
E)-x=9
F)-x=-6
G)-3x=-45
H)24=2x

Answer 1

Boa noite

a)2x = 16
x = 16 / 2
x = 8

b) 3x = -21
x = -21/3
x = -7

c)36x = 0
x = 0/36 = 0

d)14x = 56
x = 56 / 14
x = 4

e)-x = 9 ×(-1)
x = -9

f) -x = -6 ×(-1)
x = 6

g)-3x = -45
x = -45/-3
x = 15

h) 24 = 2x
x = 24/2
x = 12


Bons estudos!

Answer 2

A)2x=16
x = 16 /2
x = 8

B)3x=-21
x = - 21/3
x = -7

C)36x=0
x = 0/36
x  = 0 

D)14x=56
x = 56 / 14
x = 4
E)-x=9   (-1)
x = -9

F)-x=-6
x = 6

G)-3x=-45
x = -45 /-3
x = 45/3
x = 15

H)24=2x
x = 24 / 2
x = 12
