Question

Questão 08 -Resolva as equações em Z:
a) 6x = 2x +16
d) 5x +7= 4x +10
b) 2x-5 = x +1
e) 4x -10 = 2x +2
c) 2x +3 = x +4
f) 4x-7 = 8x-2​

Answer 1

Resposta:

A) 6x = 2x +16

6x-2x = 16

4x=16

x=16/4

x=4

D) 5x +7= 4x +10

5x-4x = 10-7

x=3

b) 2x-5 = x +1

2x-5=1+5

x=6

e) 4x -10 = 2x +2

4x-2x=2+10

2x=12

x=12/2

x=6

c) 2x +3 = x +4

2x-x=4-3

x=1

f) 4x-7 = 8x-2

4x-8x=-2+7

-4x=5

x= 5/-4
