Question

Simplifique e resolva as equaçoes

a)4x-3-x+ 8=11
b)6.(x-2)=12
c)10x+4(3-2x)-6=8
d)3 (5+3x)+5(x-1)=22
e) 2 (9x-4)-(7+6-5x)3=18
F)9+2.(5x-4)=21

Answer 1

a)3x=11-8+3
3x=6
×=6/3
×=2

b) Distributiva
6x-12=12
6x=12+12
6x=24
×=24/6
x=4

c)10x+12-8x-6=8
2x=8-6
2x=2
x=2/2
x=1

d)15+9x+5x-5=22
14x=22-10
14x=12
x=12/14
x=6/7

e)18x-8-21-18+15x=18
33x=18+47
33x= 65
x=65/33

f)9+10x-8=21
10x=21-1
10x=20
×=20/10
x=2
espero ter ajudado!
