Question

PLIS AIUDAAAAAAAA DOY 20 PUNTOS

Answer 1

Explicación paso a paso:

1.

3x+2=2x+8

×=6

2.

x+3x+5=x+2x+3+6

4x+5=3x+9

x= 4

3.

3x+6+4x-2+11x-4=36

18x =36

x=2

4.

2x-5=5(x-4)

2x-5=5x-20

-5+20=3x

15=3x

5=x

5.

4x+2 =5x-11

13=x

6.

5x-14=3x+8-(x-8)

5x-3x= 8-x +8+14

2x+x= 30

3x=30

x=10

7.

2(x+3)=3x-8

2x+6=3x-8

14=x

8.

x+3(x-2)=2x-4

x+3x-6=2x-4

4x-6=2x-4

2x= 6-4

2x=2

x=1

9.

3(x+1)=2(x-8)

3x+3=2x-16

x=-16-3

x= -19

10.

x+3x+2(x-1)=5x+18

4x+2x-2=5x+18

6x-5x= 18+2

x= 20
