Question

me ayudan con los procedimientos

Answer 1

Respuesta:

a. 3+x+2 = 19

5 + x = 19

x = 19 - 5

x = 4

b. 12 - x + 4 = 6

16 - x = 6

-x = 6 -16

-x = -10

Multiplicamos por (-) a toda la ecuación, para asi obtener un valor positivo :

x = 10

c. 5 -7*x = -9

5 - 7x = -9

5 + 9 = 7x

14 = 7x

7x = 14

x = 14/7

x = 2

d. 7/x + 2 = 16

7/x = 16 - 2

7/x = 14

7 = 14x

14x = 7

x = 7/14

Simplificamos

x = 1/2

e. 14/2 + x = 21

7 + x = 21

x = 21 - 7

x = 14

f. 8 + 5/x - 1 = 5

8 - 1 + 5/x = 5

7 + 5/x = 5

5/x = 5 - 7

5/x = -2

5 = -2x

-2x = 5

x = -5/2

g. 32 - x/2 = 10

32 - 10 = x/2

22 = x/2

22(2) = x

x = 44

Espero te sirva de ayuda.

Answer 2

a) 3 + 2x = 19
2x = 16
x= 16/2
x= 8
b) 12 - x + 4 = 6
-x = 6 - 4 - 12
-x = -10
x= 10
c) 5 - 7x = -9
-7x = -9 - 5
-7x = -14
x = -14/-7
x = 2
d) 7/x + 2 = 16
7/x = 16 - 2
7/x = 14
x = 98
e) 14/2 + x = 21
7 + x = 21
x = 21 - 7
x = 14
f) 8 + 5/x - 1 = 5
5/x = 5 - 8 + 1
5/x = - 2
x = -10
g) 32 - x/2 = 10
- x/2 = 10 - 32
- x/2 = - 22
- x = -44
x = 44
