Question

Aplica la propiedad distributiva y resuelve.
7(x - 5) - x = 3
- 3(2x - 5 - 5x= 3x
7(x-2) - 6x + 1 = 3 - 4x
4x + 2(2x - 5) = (x - 3) - (8 - x)
9x - 2(x - 4x) = 3x - 2(3 - x)
​

Answer 1

Respuesta:

a. 7x -35-x = 3........ 6x = 38........x = 19/3

b. - 6x + 15 - 5x = 3x.... -11x -3x = -15......... -14x = -15.........x = 15/14

c. 7x - 14 - 6x +1 = 3 - 4x... x + 4x = 3 + 13...... 5x = 16 ------ x = 16 /5

d. 4x + 4x - 10 = x - 3 - 8 + x -------- 6x = -1 --------- x = -1/6

e. 3 + 48 - 8x = -2x + 10 ---------- 51 - 10 = -2x + 8x ------ 41 = 6x ------  41/6 = x

f. 9x - 2x + 8x = 3x - 6 + 2x ------ 15x - 5x = -6 -------- 10x = - 6 ..... x= - 6/10 .                      ....................................................................x = - 3/5
