Question

xfa ayúdenme con estooooOOOOo
tiene q ser con prueba​

Answer 1

Explicación paso a paso:

A. 9x-45+4x-16 =4

9x+4x =4+45+16

13x = 65

x=65/13

x=5

B. 2x-3+x-35 =2-9x-4

2x+x =2-4+3+35

3x =36

x =36/3

x=12

C. 3(x-2)+9 =0

3x-6+9=0

3x =0+6-9

3x = -3

x = -3/3

x = -1

D. 8x+7-2x+5 =4x+12- (x-30)

8x-2x+7+5 =4x-x+12+30

6x+12 =4x-x+12+30

6x+12 =3x+42

6x-3x =42-12

3x =30

x =30/3

x=10

E. 2 (3x-2)- (x+3) =8

6x-4-x-3 =8

6x-x =8+4+3

5x =15

x=15/5

x=3

F. 2 (13+x) =41+x

26+2x =41+x

2x-x =41-26

x = 16

MUY FÁCIL!! ;)
