Math, microeconomics or criminal justice
S=x-2 = smallest number
M=x = middle number
L=x+2= largest number
7S+2L =-91
7(x-2)+2(x+2) =-91
7x-14 +2x+4 =-91
9x =-91 +14-4 =-81
x =-81/9 =-9
x-2 = -11
x+2 = -7
the 3 numbers are -11, -9, and -7. -11 is the smallest, -7 is the largest
7 times smallest = -77
2 times largest = -14
-77-14 = -91
