Question

Resolva as seguintes equaçoes:
A) x+5=8
B)x+4=3
C)x+6=5
D)3x=15
E)2x=14
F)4x=-12

Answer 1

a) x= 8 - 5

x = 3

b) x= 3 - 4

x= -1

c) x= 5 - 6

x= -1

d) 3x = 15

x= 15/3

x= 5

e) 2x = 14

x= 14/2

x=7

f) 4x = -12

x = -12/4

x= - 3

Answer 2

A ) x + 5 = 8

x = 8 - 5

x = 3

B ) x + 4 = 3

x = 3 - 4

x = - 1

C ) x + 6 = 5

x = 5 - 6

x = - 1

D ) 3x = 15

x = 15/3

x = 5

E ) 2x = 14

x = 14/2

x = 7

F ) 4x = - 12

x = - 12 / 4

x = - 3
