Question

Consigna. Resuelvan las siguientes ecuaciones.

1) 5X + 1 = 3X -4

2) 7X - 3 = 9X + 5

3) 5X + 3 = 2X + 9​

Answer 1

Respuesta:

!hola!

Explicación paso a paso:

1) 5x + 1 = 3x - 4

4 + 1 = - 5x + 3x

5 = - 2x

x = - 2 - 5

x = -7

x = √7

x= 2.6

2) 7x - 3 = 9x + 5

- 5 - 3 = - 7x + 9x

- 8 = 2x

x = 8 + 2

x = 10

x = √10

x = 5

3) 5X + 3 = 2X + 9

- 9 + 3 = - 5x + 2x

- 6 = - 3x

x = 6 - 3

x = 3

x = √3

x = 1.7
