EQUAÇÕES: SENDO U=Q
16x - 1 =12x + 3
3x - 2 = 4x + 9
5x - 3 + x = 2x + 9
17x - 7x = x +18
5x + 6x - 16 =3x + 2x - 4
5x + 4= 3x - 2x + 4

Answer 1

1.16x-1=12x+3
16-12x=3+1
4x=4
x=4/4
x1

2.3x-2=4x+9
3x-4x=11
-1x=11
x=11/-1
x=-11

3.5x-3+x=2x+9
5x+x-2x=9+3
4x=12
x=12/4
x=3

4.17x-7x=x+18
17x-7x-x=18
9x=18
x=18/9
x=2

5.5x+6x-16=3x+2x-4
5x+6x-3x-2x=-4+16
6x=12
x=12/6
x=2

6.5x+4=3x-2x+4
5x+2x-3x=4-4
4x=0
x=0/4
x=0
