-x-5+4x=-7x+6x+15
3x-2x=3x+2
2-4x=32-18x+12
2x-1=-3+x+4
3x-2-2x-3=0 Gente respd a equação , sendo U=Q

Answer 1

-x-5+4x=-7x+6x+15
-x+4x+7x-6x=15+5
3x+x=20
4x=20
x=20/4
x=5
3x-2x=3x+2
3x-2x-3x=2
3x-5x=2
-2x=2.(-1)
2x=-2
x=-2/2
x=-1
2-4x=32-18x+12
-4x+18x=32+12-2
14x=44-2
14x=42
x=42/14
x=3
2x-1=-3+x+4
2x-x=-3+4+1
x=-3+5
x=2
3x-2-2x-3=0
3x-2x=3+2
x=5

Answer 2

- x - 5 + 4 x = - 7 x + 6 x + 1 5
- x + 4 x + 7 x - 6 x = 1 5 + 5
1 0 x = 2 0
x = 2 0 / 1 0
x = 2

2 - 4 x = 3 2 - 1 8 x + 1 2
4 x + 1 8 x = 1 2 + 3 2 - 2
2 2 x = 4 2
x = 4 2 / 2 2

2 x - 1 = - 3 + x + 4
2 x - x = 4 + 3 + 1
1 x = 8
x = 8 / 1
x = 8

3 x - 2 - 2 x - 3 = 0
3 x - 2 x = 0 + 3 + 2
1 x = 5
x = 5 / 1
x = 5
