Question

Gente, por favor tem mais algumas equações que preciso resolver. Sou péssima com a matemática :( 

a: x-6 = x-1
    2        3

b: x +4 = 1
   3

c: x + 4 =1
          3

d: x + 4 = 1 
               3

e: 2  x+ 6 = 4 
    3             5

Answer 1

$\frac{x-6}{2}=\frac{x-1}{3}\\\\\ 3(x-6) = 2(x-1)\\\\ 3x-18 = 2x-2\\\\ 3x-2x = -2+18\\\\ \boxed{x=16}\\\\\ \frac{x}{3}+4=1\\\\ x+12=3\\\\ \boxed{x=-9}\\\\\\\ x+\frac{4}{3}=1\\\\\ 3x+4=3\\\\\ 3x = -1\\\\ \boxed{x=-\frac{1}{3}}\\\\\\\\ x+4 = \frac{1}{3}\\\\\ 3x+12=1\\\\\ 3x = -11\\\\ \boxed{x=-\frac{11}{3}}\\\\\\\\ \frac{2x}{3}+6 = \frac{4}{5}\\\\\\ 10x+90=12\\\\\ 10x =-78\\\\ \boxed{x=-\frac{39}{5}}$

Answer 2

a) 
$\frac{x-6}{2}=\frac{x-1}{3}\\ \\ 3(x-3)=2(x-1) \\ \\ 3x-18=2x-2\\ \\ \boxed{x=16}$

b)
$\frac{x}{3}+4=1 \\ \\ x+12=3\\ \\ \boxed{x=-9}$

c)
$x+\frac{4}{3}=1\\ \\ 3x+4=3\\ \\ 3x=-1\\ \\ \boxed{x=-\frac{1}{3}}$

d)
$x+4=\frac{1}{3}\\ \\ x=\frac{1}{3}-4\\ \\ \boxed{x=-\frac{11}{3}}$

e)
$\frac{2x}{3}+6=\frac{4}{5}\\ \\ 10x+90=12\\ \\ 10x=12-90\\ \\ 10x=-78\\ \\ x=-\frac{78}{10}\\ \\ x=\frac{39}{5}$
