Answer 1

Respuesta:

x= 9, 2, 8

Explicación paso a paso:

a) 2x - 2 = 16

2x = 16 + 2

x = 18/2

x = 9

Comprobacion.

2(9) - 2 = 16

18 -2 = 16

b) 7x + 2 = 16

7x = 16 - 2

x = 14/7

x = 2

Comprobacion.

7(2) + 2 = 16

14 + 2 = 16

c) 12x - 5 = 7x + 35

12x - 7x = 35 + 5

5x = 40

x =40/5

x = 8

Comprobacion.

12(8) - 5 = 7(8) + 35

96 -5 = 56 + 35

91 = 91
