Answer 1

Respuesta:

1) 2. (2+3=5)

2) x=3 (6+1=7)

3) x=7 (21+5=26)

4)5x+1 = 2x+16

    5x - 2x = 16 - 1

    3x = 15

    x = 5

5)

2x - 4 = 5x + 1

-4 - 1 = 5x - 2x

-5 = 3x

x = -5/3

6)

x + 2x + 3x = 18

6x = 18

x = 3

7)

2x+ 3x + 5x = 10

10x = 10

x = 1

8)

x + x +x +x +x = 5

5x = 5

x = 1

9)

x + 2x = 5 - 23

3x = -18

x = -6

Espero te sirva!
