Answer 1

Respuesta:

a) x = 6

b) x = 4

c) x = 2

Explicación paso a paso:

a) 8x + 7 = 6x +19

= 8x - 6x = 19 - 7

= 2x = 12

= x = 12/2

= x = 6

b) 5x - 26 = 2x - 14

= 5x - 2x = - 14 + 26

= 3x = 12

= x = 12/3

= x = 4

c) 9.2x + 6.8 = 4.8x + 15.6

= 9.2x - 4.8x = 15.6 - 6.8

= 4.4x = 8.8

= x = 8.8/4.4

= x = 2
