Answer 1

Explicación paso a paso:

4x-9+x=8+2x+13

5x-9=2x+21

5x-2x=21+9

3x=30

x=30/3

x=10

17+9x-6-x=x+35+x

11+8x=2x+35

8x-2x=35-11

6x=24

x=24/6

x=4

21+10x-19=7x+30-4x

10x+2=3x+30

10x-3x=30-2

7x=28

x=28/7

x=4

3(x+7)+2(x+3)=x+39

3X+21+2X+6=x+39

5X+27=x+39

5X-X=39-27

4X=12

X=12/4

X=3

2(3+6x)-5=7(x+8)

6+12X-5=7X+56

12X+1=7X+56

12X-7X=56-1

5X=55

X=55/5

X=11

5(4x+3)-8=(2+4x)+17

20X+15-8=2+4X+17

20X+7=4X+19

20X-4X=19-7

16X=12

X=12/16

X=3/4

23+7(x-3)=2(x+11)

23+7X-21=2X+22

7X+2=2X+22

7X-2X=22-2

5X=20

X=20/5

X=4
