Resolva as equações:
4x-6=22
9-x=2x
8+4x=6x-4
3x + 1= x +9
4x-11=7- 2x
13x +1-10x = 5 + x

Answer 1

4x-6=22
4x=22+6
4x=28
x=28/4
x=7

9-x=2x
2x=9-x
2x+x=9
3x=9
x=9/3
x=3

8+4x=6x-4
6x-4=8+4x
6x-4x=8+4
2x=12
x=12/2
x=6

3x + 1= x +9
3x-x=9-1
2x=8
x=8/2
x=4

4x-11=7- 2x
4x+2x=7+11
6x=18
x=18/6
x=3

13x +1-10x = 5 + x
13x-10x-x=5-1
2x=4
x=4/2
x=2
