Question

Resolver las siguientes ecuaciones 1. 4-8v=6-3v 2. 3x+6x-1=12+2x 3. 19x-2=12-15x 4.2x-10=4x-36 5. 5u-3u=5-3u 6. 2u+6=5u-3

Answer 1

Respuesta:

1. 4 - 8v = 6 - 3v

3v - 8v = 6 - 4

-5v = 2

v = 2 + 5

v = 7

2. 3x + 6x - 1 = 12 + 2x

-2x + 3x + 6x = 12 + 1

7x = 13

x = 13 - 7

x = 6

3. 19x - 2 = 12 - 15x

15x + 19x = 12 + 2

34x = 14

x = 14 - 34

x = -20

4. 2x - 10 = 4x - 36

-4x + 2x = -36 + 10

-2x = -26

x = -26 + 2

x = -24

5. 5u - 3u = 5 - 3u

3u + 5u - 3u = 5

5u = 5

u = 5 - 5

u = 0

6. 2u + 6 = 5u - 3

2u + 5u = -3 - 6

7u = -9

u = -9 - 7

u = -16
