Question

Nececito resolver esta ecuacion con propiedades distributivas =
4-2*(3-x)+5x-7=12x-19

Answer 1

4 - 2 (3 - x) + 5x - 7 = 12x - 19

2x - 6 + 5x - 3 = 12x - 19

7x - 9 = 12x - 19

7x - 12x = - 19 + 9

- 5x = - 10

x = - 10/-5

x = 2

Solución : 

x = 2

Answer 2

4-6x-2x+5x-7=12x-19 4-4x+5x-7=12x-19 4-9x-7=12x-19 -9x-12x=-19 -4+7 -4x=-16 X=-16:-4 X=4
