Question

I need help with this. Plspslpsss help me

Answer 1

Step-by-step explanation:

1. k = 32

k + 19 = 51

32 + 19 = 51

51 = 51

correct, so, k=32 is a valid solution.

2. x = 43

16 = x - 27

16 = 43 - 27

16 = 16

correct, so, x = 43 is a valid solution.

3. m = 9

28 - m = 17

28 - 9 = 17

19 = 17

wrong. so, m = 9 is NOT a valid solution.

4. y = 8

y + 19 = 27

8 + 19 = 27

27 = 27

correct, so, y = 8 is a valid solution.

5. p = 22

19 = p + 3

19 = 22 + 3

19 = 25

wrong. so, p = 22 is NOT a valid solution.

6. r = 11

4 + r = 15

4 + 11 = 15

15 = 15

correct, so, r = 11 is a valid solution.

7.

a - 8 = 9 adding 8 to both sides

a = 17

8.

v + 13 = 15 subtracting 13 from both sides

v = 2

9.

16 = n - 24 adding 24 to both sides

40 = n or n = 40, of course

10.

c - 9 = 16 adding 9 to both sides

c = 25

11.

11 + k = 18 subtracting 11 from both sides

k = 7

12.

15 = w - 7 adding 7 to both sides

22 = w or w = 22, of course
