Question

simplifique e resolva as equaçoes a)4x-3-x+ 8=11b)6(x-2)=12c)10x+4(3-2x)-6=8d)3(5+3x)+5(x-1)=22e) 2(9x-4)-(7+6-5x)3=18       (com conta pf)

Answer 1

a) 4x-3-x+8=11 b) 6 (x-2)= 12
3x=11-8+3 6x-12=12
x=6/3 x=24/6
x=2 x=4

c) 10x+4 (3-2x)-6=8 d) 3 (5+3x)+5 (x-1)=22
10x+12-8x-6=8 15+9x+5x-5=22
2x=8-6 14x=22-10
x=2/2 x=12/14
x=1 x=0,857142857

e) 2 (9x-4)-(7+6-5x)3=18
(18x-8)-(21+18-15x)=18
18x-8-39+15x=18
33x=18+47
x=65/33
x=1,969696

uffaaaa acabei espero ter ajudado
