Question

Resolva as equações:

1-) 5x - 3x-1/2 = 4
2-) 5-2x/2 = 22/4
3-) x - x/2 = 1
4-) x/2 + x/4 + x/2 = 4
5-) x-1/2 + x-3/3 = 6

Valendo 20 pontos :3

Answer 1

1-) 5x-3x-1/2=4
    5x-3x-1=8
     2x=7
      x=7/2

2-) 5-2x/2=22/4
    5-2x=22/2
    5-2x=11
    2x=-6 --> x=-3

3-) acho que voce copiou essa errada

4-)x/2 + x/4 + x/2 = 4
    2x+x+2x=16
   5x=16 ---> x=16/5

5-)x-1/2 + x-3/3=6 
     3x-3 + 2x - 6 = 6
    5x - 6 = 6 
    5x = 12 --> x=12/5

Answer 2

1) 5x-3x-1/2= 4
Tire o mmc
10x-6x-1 =4
4x = 4 + 1
X= 5/4
