Answer 1

Explicación paso a paso:

1.

2x-7=-3

2x=-3+7

2x=4

x=4÷2

x=2

2.

3x+5=-1

3x=-1-5

3x=-6

x=-6÷3

x=-2

3.

2x-8=10

2x=10+8

2x=18

x=18÷2

x=9

4.

5x-7+2x=4x+5

5x-7x=4x+5-2

-2x=4x+5-2

-2x-4x=5-2

-6x÷3=3÷3

-2x=1

2x=-1

5.

5x-2x-4=x+7-5

5x-2x=x+7-5+4

5x-2x-x=7-5+4

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

5x-2x-x=2

3x-x=2

2x=2

x=2÷2

x=1

6.

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

x-2x-1=8-3x-3

-x-1=8-3x-3

-x-1=5-3x

-x-1+3x=5

-x+3x=5+1

2x=6

x=6÷2

x=3

7.

2(x-1)-3=14-x

2x-1-3=14-x

2x-1=14-x+3

2x=14-x+3+1

2x+x=14+3+1

3x=17+1

3x=18

x=18÷3

x=6

8.

15x-10=6x-(x-2)+(-x+3)

15x-10=6x-x+2-x+3

15x=6x-x+2-x+3+10

15x+x=6x-x+2+3+10

15x+x-6x=-x+2+3+10

15x+x-6x+x=2+3+10

15x+x-6x+x=5+10

15x+x-6x+x=15

16x-6x+x=15

10x+x=15

11x=15

x=15/11

9.

x+3(x-1)=6-4(2x+3)

x-3x+3=6-8x-12

x-3x+8x=6-12-3

x-3x+8x=6-3

x-3x+8x=3

-2x+8x=3

6x=3

x=3/6

10.

6-3(x-1)=-4x+2(1-x)

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

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

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

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

-3x+4x+2x=-10

1x+2x=-10

3x=-10

x=-10/3
