a crate contains apples, pears, and oranges.There are 184 apples and pears and 248 apples and oranges. there are 3 times as many oranges as pears. how many apples are in the crate?
How do I show my work to solve this problem using Singapore math  Math in Focus curriculum?

no idea what
Singapore math  Math in Focus curriculum?
is
but here is how I would do this
let the number of pears be x
then the number of oranges is 3x , it said so
let the number of apples be a
a+x = 184
a + 3x = 248
subtract them
2x = 64
x = 32
sub back into
a+x=184
a+32 = 184
a = 152
so we have
152 apples
32 pears and
96 oranges
