-3/5 = (f-g))/(11-f))
we use cross products to help solve the problem
top on the left times bottom of the right = top on the right times bottom on the left
5(f-g)= -3(11 - f)
distribute
multiply the number on the outside of the parenthesis to the terms on the inside
5*f -5*g = -3*11 -3* (-f)
5f-5g = -33 +3f
subtract 3f from each side
2f -5g = -33

Answer:
10 pieces
Step-by-step explanation:
Total no. of pieces of calzone = 24
No of pieces of calzone eaten by sophie = 1/4 of Total no. of pieces of calzone = 1/4 of 24 = (1/4)*24= 6 pieces.
No of pieces of calzone eaten by Glenn = 1/4 of Total no. of pieces of calzone = 1/4 of 24 = (1/4)*24= 6 pieces.
Total no of pieces eaten by both of them on saturday = 12.
No of pieces of calzone left = 24-12 = 12
_______________________________________________
No of pieces of calzone eaten by Glenn on next day = 1/6 of Total no. of pieces of calzone left= 1/6 of 12 = (1/6)*12= 2 pieces
No of pieces of calzone left now after Glenn ate 2 of them = 12-2 = 10.
Thus 10 pieces of original calzone are left .
