Answer:

Step-by-step explanation:

Lets start with 13

-2(13 + 3) = -4(13) + 20

-32 = -52 + 20

-32 = -32

x = 1 basically

now 19

-2(19 + 3) = -4(19) +20

-44 = -76 + 20

-44 = -56

so divide those

-2(31 + 3) = -4(31) + 20

-68 = -124 + 20

-68 = -104

divide them

-2(37 + 3) = -4(37) + 20

-80 = -148 + 20

-80 = -128
