Answer 1

Resposta:

4x-7=x-2

4x-x=-2+7

3x=5

x= 5/3

2x+1=4x-7

2x-4x=-7-1

-2x=-8

x=-8/-2 x=4

9x+9=15-3x

9x+3x=15-9

12x=6

x=6/12 x=3/6 x=1/2

16x-1=12x+3

16x-12=3+1

4x=4

x=4/4 x=1

3x-2=4x+9

3x-4x=9+2

-1x=11

x=11/-1 x=-11

5x-3+x=2x+9

5x+x-2x=9+3

4x=12

x=12/4 x= 3

17x-7x=x+18

17x-7x-x=18

9x=18

x=18/9 x=2

2x-4=18-2x

2x+2x=18+4

4x=22

x=22/4 x=11/2

x+2x+3-5x=4x-9

x+2x-5x-4x=-9-3

-6x=-12

x=-12/-6 x=2

5x+6x-16=5x=4

5x+6x-5x=4+16

6x=20

x=20/6 x=10/3
