Answer 1

hey hiiiiii dude here is u r answer ☺

6. 7x + 4 = 25

7x = 25 - 4

7x = 21

x = 21/7

x = 3

so, your option is D

7. 3X + 7 = -20

3x = -20 + 7

3x = -13

x = -13/3

so, u r option is D

9. k + 7 = 16

k = 16-7

k = 9

8k - 72 = 8(9) - 72

= 72 - 72 = 0

so, u r option is A

10. 43m = 0.086

m = 0.086/43

m = 0.02

so,u r option is B

12. 3 + x = 8

x = 8 - 3

x = 5

so, u r option is D

13. 10 + 3x = 1

3x = 1 - 10

3x = -9

x = -9/3 = -3

so, u r option is B

Answer 2

Answer:

6.  D

7. D

9. A

10. B

12. D

13. B

Step-by-step explanation:

6. 7x + 4 = 25, 7x = 25 - 4, 7x = 21, x = 21/7, x = 3

7. 3X + 7 = -20, 3x = -20 + 7, 3x = -13, x = -13/3

9. k + 7 = 16, k = 16-7, k = 9, 8k - 72 = 8(9) - 72, = 72 - 72 = 0

10. 43m = 0.086, m = 0.086/43, m = 0.02

12. 3 + x = 8, x = 8 - 3, x = 5

13. 10 + 3x = 1, 3x = 1 - 10, 3x = -9, x = -9/3 = -3
