Question

ecuaciones:

5x = 250 . 3

6x - 5 = 3x + 4

6 x + 2 = 18 + 2x

5x + 2 + x = 2× + 6 + 2x

Answer 1

Respuesta:

5x = 250 × 3

5x = 750

x = 750/5 = 150

6x - 5 = 3x + 4

6x - 3x = 4 + 5

3x = 9

x= 9/3 = 3

6x + 2 = 18 + 2x

6x - 2x = 18 - 2

4x = 16

x= 16/4 = 4

5x + 2 + x = 2 × +6 + 2x

5x + x - 2x = 2 × +6 -2

4x = 8

x = 8/4 = 2
