Question

Resuelve las sig. ecuaciones.
a) 16 = 4 ( m + 2 )
b) 8 ( x - 3 ) = 24
c)15 = 5 ( x - 2 )
d) - 4 ( x - 6 ) = -4
e)4 ( 3x - 1 ) = 2 ( 2x + 6 )

Answer 1

a) 16 = 4 ( m + 2 )
16 = 4 m + 8
16 - 8 = 4 m
8 = 4 m
2 = m
——————————
b) 8 ( x - 3 ) = 24
8x - 24 = 24
8x = 24 + 24
8x = 48
x = 6
——————————
c)15 = 5 ( x - 2 )
15 = 5x - 10
15 + 10 = 5x
25 = 5x
5 = x
——————————
d) - 4 ( x - 6 ) = -4
-4x + 24 = -4
-4x = -4 - 24
-4x = - 28
x = 7
——————————
e)4 ( 3x - 1 ) = 2 ( 2x + 6 )
12 x - 4 = 4x + 12
12x - 4x = 12 + 4
16 x = 16
x = 1
