Answer 1

Answer:

sorry please ask only one or two questions

Answer 2

Answer :

7x + 4 = 25

7x = 25 - 4

7x = 21 x = 21/7

x = 3

so, your option is D

$\rule{100}{2}$

7. 3X + 7 = -20

3x = -20 + 7

3x = -13

x = -13/3

so, u r option is D

$\rule{100}{2}$

9. k + 7 = 16

k = 16-7

k = 9

8k - 72 = 8(9) - 72 = 72 - 72 = 0

so, u r option is A

$\rule{100}{2}$

10. 43m = 0.086

m = 0.086/43

m = 0.02

so,u r option is B

$\rule{100}{2}$

12. 3 + x = 8

x = 8 - 3

x = 5

so, u r option is D

$\rule{100}{2}$

13. 10 + 3x = 1

3x = 1 - 10

3x = -9 x = -9/3 = -3

so, u r option is B
