Es para hoy lo necesito porfiii

Answer 1

ACTIVIDAD 1 : RESUELVA LAS SIGUIENTES ECUACIONES.

A- 15 X - 24 = 3 X

15 X - 3 X = 24

12 X = 24

X = 2

B- 4 X - 5 = 2 X - 9

4 X - 2 X = -9 + 5

2X = - 4

X= - 2

C- X + 11 = 23 + 5 X

X - 5 X = 23 - 11

- 4 X = 12

X = - 3

D - X - 9 = 4

X = 4 + 9

X = 13

E- 6 X + 2 = 1 + 2 X

6 X - 2 X = 1- 2

4 X = - 1

X = - 1/ 4

F- 3 ( X - 5 ) = 19 - ( X - 2)

3 X - 15 = 19 - X + 2

3 X - 15 = 21 - X

3 X + X = 21 + 15

4 X = 36

X = 9

G- 3 X - 5 = 19 - ( X - 2 )

3 X - 5 = 21 - X

3 X + X = 21 + 5

4 X = 26

X = 13 / 2

H- 5 ( X + 3 ) + 2 ( X - 7 ) = 3 X - 1

5 X + 15 + 2 X - 14 = 3 X - 1

7 X + 1 = 3 X - 1

7 X - 3 X = - 1 - 1

4 X = - 2

X = - 1 / 2
