Question

Me ayudais???


a) 13 – 5x + 3 ( 2x – 4 ) = 23 – 3 ( x – 2 )




b) 10 – 2 = 6 – 5 ( x – 4 )

Answer 1

Respuesta:

a) 13 – 5x + 3 ( 2x – 4 ) = 23 – 3 ( x – 2)

13 – 5x + 6x - 12 = 23 – 3x + 6

1 + x = 29 - 3x

4x = 28

X = 7

b) 10 – 2 = 6 – 5 ( x – 4 )

8 = 6 – 5x + 20

5x = 18

X = 18/5
