Question

resuelve los siguientes ejercicios

a. 7 (x-5)-x=3

b. -3(2x5)-5x=3×

c. 7(x-2)-6x+1=3-4x

d. 4×+2(2x-5)=(x​-3)-(8-x)

Answer 1

Explicación:

a) 7x - 35 - x = 3

6x = 38

x = 19/3

b) -3(10) - 5x = 3x

-30 = 8x

-15/4 = x

c) 7x - 14 - 6x + 1 = 3 - 4x

x - 13 = 3 - 4x

5x = 16

x = 16/5

d) 4x + 4x - 10 = x - 3 - 8 + x

8x - 10 = 2x - 11

6x = - 1

x = -1/6
