Answer 2

Respuesta:

5. x=24

6. x=27

7. x=28

8. x=9/40

9. x=450

10. x=½

Explicación paso a paso:

5. x/2 + x/3 = 20

3x/6 + 2x/6 = 20

5x/6 = 20

x/6 = 20/5

x/6 = 4

x = 4×6

x = 24

6. 2x/3 = 18

x/3 = 18/2

x/3 = 9

x = 9×3

x = 27

7. x/4 + x/7 = 11

7x/28 + 4x/28 = 11

11x/28 = 11

x/28 = 11/11

x/28 = 1

x = 1×28

x = 28

8. 5x+1/8 = 17

5x+1 = 17/8

5x = 17/8 - 1

5x = 17/8 - 8/8

5x = 9/8

x = (9/8) / (5/1)

x = 9/40

9. x/5 - x/6 = 15

6x/30 - 5x/30 = 15

x/30 = 15

x = 15×30

x = 450

10. (3x+2)/2 = 7

3x+2 = 7/2

3x = 7/2 - 2

3x = 7/2 - 4/2

3x = 3/2

x = (3/2) / (3/1)

x = 3/6

x = ½
