first let's represent their weights using variables:

let C = weight of one piece of cake

let A = weight of one apple

let H = weight of one cherry

from the first statement,

(1) 2C = A + H

for the second statement,

(2) A = 5H + C

now we need to find how mach does cherries weigh as much as 1 apple. thus we need to manipulate these equations so that the weight of cake, C will not be involved in the final equation (in other words, we'll eliminate C)

first, from equation (2), we transpose C to the left side and A to the right side, and multiply both sides by 2, and it becomes:

-2C = -2A + 10H

then we add this to equation (1):

2C = A + H

-2C = -2A + 10H

---------------------

0 = -A + 11H

A = 11H

therefore, 1 apple weighs as much as 11 cherries.

hope this helps~ :)
