Answer 1

Resposta:

a)4x-1=11-2x => 4x+2x=11+1 => 6x=12 => x=12/6 => x=2

b)9x+6=8x+4 => 9x-8x =4-6 => x=-2

c )3x-1=x+2 => 3x-x=2+1 => 2x =3 => x=3/2

d)11x+12=9x+13 => 11x-9x=13-12 => 2x=1 => x=1/2

e)x-3=3x-9 => 3x-x=-3+9 => 2x=6 => x=6/2 => x=3

f)x+5=11-3x => x+3x=11-5 => 4x=6 => x=6/4

g)6x+4=4x+12 => 6x-4x=12-4 => 2x=8 => x=8/2 => x=4

h)2x+12=24-10x => 2x+10x=24-12 => 12x=12 => x=1
