Question

Resolva as equaçoes a seguir:
a:10x+16=14x+8
b: 2 (x-3)=-3(x-3)
c: 4(5x-3)-64(3-x)-3(12x-4)=36
d: 5(x+1)+6(x+2)=9(x+3)
e: x/2 + x/3 - x/4 =14

SOS!!!!

Answer 1

a:10x+16=14x+8
16-8=14x-10x
8=4x
4x=8
 x=8/4
 x=2

b: 2 (x-3)=-3(x-3) 
  2x-6=-3x+9
  2x+3x=9+6
  5x=15
   x=15/5
   x=3

c: 4(5x-3)-64(3-x)-3(12x-4)=36
   20x-12-192+64x-36x+12=36
   20x+64x-36x-12-192+12-36=0
   84x-36x-228=0
   48x-228=0
   48x=228
      x=228/48
       x=4,75

d: 5(x+1)+6(x+2)=9(x+3) 
   5x+5+6x+12=9x+27
   11x+17=9x+27
   11x-9x=27-17
   2x=10
    x=10/2
    x=5

e: x/2 + x/3 - x/4 =14
    2x/5-x/4=14
     x/1=14
      x=14
