Question

Resolva em R as equações a seguir:

a) 3+ x = 0

b) 23x + 2 = 2

c) 12 - 7 + 4x = 25

d) 5x - 3x = 30

e) 4x + 10 = 45 - 3x​

Answer 1

Resposta:

a) 3+ x = 0

x = 0 + 3

x= 3

b)23x = 2 -2

x = 0/23

x= 0

c) 12 - 7 + 4x = 25

5 + 4x = 25 -5

4x = 20

x = 20/4

x = 5

d) 5x - 3x = 30

2x=30

x= 30/2

x= 15

e) 4x + 10 = 45 - 3x

4x + 3x = 45 -10

7x = 35

x = 35/7

x = 5
