Answer:

  1. 3x/2x + 5/1 =1/3

Step-by-step explanation:

(2x+1) 1 = (3x+5) 3

2x+1 = 9x+15

2x-9x = 15-1

-7x = 14

x= 14/-7

x= -2

Step-by-step explanation:

1. 3x+5/2x+1 = 1/3

3(3x+5) = 2x+1

9x+15 = 2x+1

9x-2x = 1-15

7x = -14

x = -14/7

x = -2

2. x+6/4+x-3/5 = 5x-4/8

5(x+6)+4(x-3)/20 = 5x-4/8

5x+30+4x-12/20 = 5x-4/8

5x+4x+30-12/20 = 5x-4/8

9x+18/20 = 5x-4/8

8(9x+18) = 20(5x-4)

72x+144= 100x -80

72x-100x = -80-144

-28x = -224

28x = 224

x = 224/28

x = 8

3. x/4+x/6 = x-7

3x+2x/12 = x-7

5x/12 = x-7

5x/12-x = -7

5x-12x/12 = -7

-7x/12 = -7

7x/12 = 7

x = 7×12/7

x = 12

4. 2/3 x +1 = 7/3

2/3 x = 7/3-1

2/3 x = 7-3/3

2/3x = 4/3

x = 4/3×3/2

x = 2
