a 56 kg miniature horse weighs 268 fewer kilograms than shetland pony
If the mini horse is 56kg and it's 268kg less than a Shetland pony then a Shetland pony would weigh 56+268=324kg
let
x--------> Shetland pony's weigh
y--------> Miniature horse's weigh
we know that
\(y=56 kg\)
\(x=268+y \\ x=268+56 \\ x=324 kg\)
the answer is
Shetland pony's weigh is \(324 kg\)
