In my number the digit in the ones place is doubled the digit in the tens place the sum of the digit is three what is my number

Xy is the number (not x times y)

x is tens place
y is the ones place

ones is double tens place and sum is 3

y=2x
x+y=3
subsitute 2x for y
x+2x=3
3x=3
divide 3
x=1
sub back
y=2x
y=2(1)
y=2

xy
12
the number is 12

Then just do it (lol)
