Question

1,Resolva as equaçoes e determine a quais conjuntos numéricos (n,z,q,ii ou r) pertence a solução cada uma delas.
a,8b-3=5b+6
b,2y+9=10-y
c,z-7=1+2z
d,5+4a=a+3
e,9w-6=8-w
    \2
f,5.(2x-1)=3.(x-4)

Answer 1

a,8b-3=5b+6  ==> 8b -5b = 6+3 ++> 3b=9 ++> b= 3  N
b,2y+9=10-y ==> 2y+y=10-9 ++> 3y=1 ==>y=1/3  Q
c,z-7=1+2z==>2z-z=-7-1==> z = - 8    Z
d,5+4a=a+3==> 4a-a=3-5==>3a= -2==> a = -2/3   Q
e,9w-6=8-w/2==>18w+w=16+12==> 19w=28==> w=28/19  Q
    
f,5.(2x-1)=3.(x-4)==>10x-5=3x-12==>10x-3x=-12+5==>7x=-7==>x= - 1   Z
