Question

Resolva as equações:

1-) x - x/2 = 1

2-) x/4 + 7 = x/2 + 5
3-) x/3 + x/2 = 7+x/3
4-) x-1/5 = 1
5-) x/3 + x/2 = 15
6-) 3x/4 - 1x/2 = -2
7-) x-2/3 - x+1/4 = 4

8-) x/3 + 4 = 2x
9-) x-2/3 + 2x = 5x/2
10-) x-5/3 + 3x-1/2 + 2x = 4
11-) x+2/2 - 5-x/2 = 1 + 2x-1/3

12-) 3x/2 - 5x = -7
13-) 2x-3/4 - 2-x/3 = x-1/3
