me ajudem 2x=16-x-9
me ajudem 7.(x-1)=2.(3x+1)
me ajudem 5x-2x=6-3x
me ajudem 4x-5=-6x+15
me ajudem x=8
5 2

me ajudem 5= x
15 60​

Answer 1

2x=16-x-9

2x+x=16-9

3x=7

x=7/3

7(x-1)=2(3x+1)

7x-7=6x+2

7x-6x=+7+2

x=9

5x-2x=6-3x

5x-2x+3x=6

6x=6

x=6/6=1

4x-5=-6x+15

4x+6x=15+5

10x=20

x=20/10=2
