Answer:

1. 3x-15=24

3x= 24+15

3x = 39

x=39/3

x= 13

2. -4x+8=9

-4x= 9-8

-4x= 1

x= -1/4

3. 4= 5p-25

4+25= 5p

29= 5p

p= 29/5

4. 34-5p-5=4

25=5p

p= 25/5

p = 5

5. 5x= 28-2

x= 26/5

6. 8x-12+15x-20=14

23x= 14+32

23x = 46

x= 46/23

x= 2

Step-by-step explanation:

1. 3x - 15 = 24

3x = 24 + 15

3x = 39

x = 39/3

x = 13

2. -4x + 8 = 9

-4x = 9 -8

-4x = 1

x = -1/4

3. 4 = 5p - 25

4 + 25 = 5p

29 = 5p

29/5 = p

p = 29/5

4. 34 - 5p - 5 = 4

-5p = 4 + 5 -34

-5p = 9 - 34

-5p = - 25

p = -25/-5

p = 5

5. 5x + 2 = 28

5x = 28 -2

5x = 26

x = 26/5

6. 8x- 12 + 15x - 20 = 14

8x + 15x = 14 +12 +20

23x = 26+20

23x = 46

x = 46/23

x = 2
