Question

resolva as equaçoes:
a)x/2=8
b)x/2= -8
c)x/4= -5
d)3x/4=9

Answer 1

a) x/2 = 8
x = 16 ( 2 passa p o outro lado multiplicando o 8)

b) x/2 = -8
x = -16 (passa p o outro lado multiplicando)

c) x/4 = -5
x= -20 (passa p o outro lado multiplicando)

d) 3x/4=9
3x=36 (passa p o outro lado multiplicando)
x=12 ( 3 passou dividindo o 36)

Answer 2

a) x= 8*2 logo x=16
b) x=-8*2 logo x=-16
c)x=-5*4 logo x=-20
d x=9*4/3 logo x=12
