Answer 1

Number 11 Answer = n = 2 || Number 12 Answer = x = 3

Explanation:

12) 4(4 - 3x) = -23 + x

1. multiply 4 times 4 and 4 times 3x

16 - 12x = -23 + x

2. subtract 16 from itself 16 and 23

-12x = -39 + x

3. subtract x from itself and -12x

-13x = -39

4. Divide -13 from itself and -39

x = 3

11) 4(3 - 4n) = -24 + 2n

1. multiply 4 times 3 and 4 times 4n

12 - 16n = -24 + 2n

2. subtract 12 from itself and 24

-16n = -36 + 2n

3. subtract 2n from itself and -16n

-18n = -36

4. Divide -18n from itself and -36

n = 2

Answer 2

9) no solution

10) p = 4

11) n = 2

12) x = 3

Explanation:

9) -5 ( -v - 4) + 4v = v + 20

5v + 20 + 4v = v + 20

no solution

10) -2 -3(p + 3) = -4p - 7

-2 - 3p - 9 = -4p - 7

-11 = -1p - 7

-4 = -1p

p = 4

11) 4(3 - 4n) = -24 + 2n

12 - 16n = -24 + 2n

-18n = -36

n = 2

12) 4(4 - 3x) = -23 + x

16 - 12x = -23 + x

-13x = -39

x = 3

hope this helps! :)
