Question

2-Resolva as equações:

a)
$6x = 2x + 16$
b)
$2x - 5 = x + 1$
c)
$2x + 3 = x + 4$
d)
$5x + 7 = 4x + 10$
e)
$4x + 10 = 2x + 2$
​

Answer 1

Explicação passo-a-passo:

a) 6x -2x = 16

4x = 16

x= 16÷4

x= 4

b) 2x - x = 1 +5

1x = 6

x=6

c) 2x - x = 4 -3

1x = 1

x=1

d) 4x -2x = 2 - 10

2x = -8

x= - 8/2

x= - 4
