Question

resolva as equações:

a)x+1/2+x-3/3=1/2 b)x+1/2+x+2=x

Answer 1

a) 6x + 3 + 6x - 6 = 3
12x = 3 + 3
12x = 6
x = 1/2
b) 2x + 1 + 2x + 4 = 2x
4x - 2x = - 5
2x = -5
x = -5/2

Answer 2

A) $\frac{x+1}{2} + \frac{x-3}{3}$ = $\frac{1}{2}$
 
 $\frac{(3.x+3)+(2.x-6)}{6} = [tex] \frac{1}{2}$  →   \frac{5.x-3}{6} [/tex]
 
 
Achar valor de x:
  
   $\frac{5.x}{6} - \frac{3}{6}$ = $\frac{1}{2}$

                 $\frac{5.x}{6} = \frac{3+3}{6}$
                                
                               5.x = 6  -→x =  $\frac{6}{5}$

B)  $\frac{x+1}{2} + x+2 = x$
    
     $\frac{(x+1)+2.x+4}{2}$ = x
 
             x+1+2.x+4 = 2.x
               3.x + 5 = 2.x
                3.x-2.x = -5
                        x = - 5
