9) no solution

10) p = 4

11) n = 2

12) x = 3

Step-by-step 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! :)

marco saved more.   he saved $35 more.

step-by-step explanation:

1+2+3+4+5+6+7+8+9+10 = 55

2*10 = 20

55-20 = 35
