porfa me ayudan es para mañana urgente​

Answer 1

A) 10 - x = 4

10 - 4 = x

6 = x

B) 5 + 3 = 2x

8 = 2x

8/2 = x

4 = x

C) x + 15 = 23

x = 23 - 15

x = 8

D) 2x + 2 = 20

2x = 20 - 2

x = 20/2 - 2/2

x = 10 - 1

x = 9

E) 34 - 14 + x = 34

20 + x = 34

x = 34 - 20

x = 14

F) 25x + 2 = 5x + 2

25x - 5x = 2 - 2

20x = 0

x = 0/20

x = 0

G) x - 3 = 3 - x

x + x = 3 + 3

2x = 6

x = 6/2

x = 3

H) 2x - 3 = 6 + x

2x - x = 6 + 3

x = 9

I) 2 - x = x - 8

2 + 8 = x + x

10 = 2x

10/2 = x

5 = x

J) 3x + 34 = 13

3x = 13 - 34

3x = -21

x = -21/3

x = -7
