POR FAVOR E PRO TRABALHO

Answer 1

Olá, 

a) 11x - 1 = 5x
11x - 5x = 1
6x = 1
x = 1/6 

b) 11x - 17 = 10x + 13
11x - 10x = 13 + 17
x = 30

c) 3x - 11 = x - 11
3x - x = -11 + 11
2x = 0
x = 0/2
x = 0

Answer 2

A) 11x-1=5x  ==. 11x-5x = 1 ==> 6x=1 ==> x = 1/6
===================================================
b) 11x-17=10x+13  ==> 11x-10x = 17+13 ==>  x = 30
==================================================
c)3x-11=x-11 ==> 3x-x = - 11+11 ==> 2x = 0 ==> x = 0
