Question

Resuelve las siguientes ecuaciones 2 (x + 7) = 19 x
= 3 (x - 4) = 11 x
= 5 (x - 4) = 12 x=
10 (x + 7) = 82 x=

Answer 1

2 (x + 7) = 19 x

2x + 14 = 19x

14 = 19x - 2x

14 = 17x

14/17 = x

3 (x - 4) = 11 x

3x -12 = 11x

-12 = 11x -3x

-12 = 8x

-12/8 = x

-3/2 = x

5 (x - 4) = 12 x

5x -10 = 12x

-10 = 12x - 5x

-10 = 7x

-10/7 = x

Answer 2

Respuesta:

2 (x + 7) = 19 x=  2.5 o 14/17

3 (x - 4) = 11 x=  7.66666666667  o 23/3

5 (x - 4) = 12 x= 6.4 o 32/5

10 (x + 7) = 82 x=  1.2 o 10/12
