Question

Favor resolver las siguientes 3 ecuaciones $7x=20+3x\\\\-9x=-3x+24\\\\5x-6=-4x+3$

Answer 1

Respuesta:

• 7x = 20 + 3x

- 3x + 7x = 20

4x = 20

x = 5

• - 9x = - 3x + 24

- 24 = - 3x + 9x

- 24 = 6x

- 4 = x

• 5x - 6 = - 4x + 3

5x + 4x = 6 + 3

9x = 9

x = 1

Answer 2

Respuesta:

7x = 20 + 3x

- 3x + 7x = 20

4x = 20

x = 5

- 9x = - 3x + 24

- 24 = - 3x + 9x

- 24 = 6x

- 4 = x

5x - 6 = - 4x + 3

5x + 4x = 6 + 3

9x = 9

x = 1
