resolva as seguintes equações
a)2x+4=6
b)3x-17=24
c)4x+82=100+3x
d)5x-45+6x+89=12x-87+5x+234
e)15x+4=14x​

Answer 1

Explicação passo-a-passo:

a)2x+4=6

2x=6-4

2x=2

x=2/2

x=1

b)3x-17=24

3x=24+17

3x=41

x=41/3

c)4x+82=100+3x

4x-3x=100-82

x= 18

d)5x-45+6x+89=12x-87+5x+234

5x+6x-45+89=12x+5x-87+234

11x+44=17x+147

11x-17x=147-44

-6x=103

x=103/-6

x=-103/6

e)15x+4=14x

15x-14x=-4

x= -4
