Answer 1

Answer:

• 81/x - 3 = 6
• 2x - 3 = 15

Answer 2

Answer:

it's only the last two

Step-by-step explanation:

3x + 2 = 25

3x + 2 - 2 = 3x

25 - 2 = 23

3x = 23

3x / 3 = x

23 / 3 = 7 2/3

x = 7 2/3 not this one

x/3 + 7 = 8

x/3 + 7 - 7 = x/3

8 - 7 = 1

x/3 = 1

x/3 * 3 = x

1 * 3 = 3

x = 3 not this one

4 + 5x = 18

4 + 5x - 4 = 5x

18 - 4 = 14

5x = 14

5x / 5 = x

14 / 5 = 2 4/5 not this one

24 - 2x = 13

24 - 2x - 24 = -2x

13 - 24 = -11

-2x = -11

-2x / -2 = x

-11 / -2 = 5 1/2 not this one

81/x - 3 = 6

81x - 3 + 3 = 81/x

6 + 3 = 9

81/x = 9

81/x * x = 81

9 * x = 9x

81 = 9x

81 / 9 = 9

9x / 9 = x

9 = x this one

2x - 3 = 15

2x - 3 + 3 = 2x

15 + 3 = 18

2x = 18

2x / 2 = x

18 / 2 = 9

x = 9 this one
