Answer 1

OKAY,VAMOS LÁ:

A)3X-3-2X+6=36
3X-2X=36+3-6
X=33

B)10X+16=14+8
10X=22-16
10X=6
X=6/10 ÷2 -> X=3/5

C=6X-6=-3X-9
6X+3X=-9+6
9X= -3
X= -3/9 ÷ 3 -> X=-1/3

D)É A MESMA OPERAÇÃO DA LETRA C) !!!

E)20x-12-2x-4x=96
20x-6x=96+12
14x=108
x=108/14 ÷2 -> x= 54/7

F)5X+5+6X+12=96
11X=96-5-12
11X=96-17
11X=79
X=79/11
