Alguien que me ayude.

Answer 1

Hola

1. 5x=8x-15

5x-8x=-15

-3x=-15

3x=15

x=5

2. -y-5=3y-25

-y-3y=-25+5

4y=20

y=20/4

y=5

3. 4x+1=2

4x=2-1

4x=-1

x=-1/4

4. 5x+6=10x+5

5x-10x=5-6

5x=-1

x=-1/5

5. 9y-11=-10+12y

9y-12y=-10+11

-3y=1

y=1/-3

6. 8x-4+3x=7x+x+14

11x-4=8x+14

11x-8x=14+16

3x=30

x=30/3

x=10

7. 8x+8-12x=4x-13-5x

-4x+8=-x-13

-4x+x=-13-8

-3x=-21

3x=21

x=21/3

x=7

8. 5y+6y-81=7y+102+65y

11y-81=72y+102

11y-72y=102+81

61y=183

y=183/61

y=3

9. 2(x+3)-4x+1=3(2x-6)+17

2x+6-4x+1=6x-18+17

-2x+7=6x-1

-2x-6x=-1-7

-8x=-8

8x=8

x=1

10. 5x-15+10x=2(6x+3)

15x-15=12x+6

15x-12x=6+15

3x=21

x=21/3

x=7

Espero haberte ayudado
