Hello,
The word sum is translated to addition. This can be solved using variables. We can represent the smaller number with n and the larger number with n + 12.
Equation -> n + n + 12 = 36
Combine like terms: n + n = 2n
Equation -> 2n + 12 = 36
Use inverse of addition and subtract 12 from both sides
Equation -> 2n = 24
Use inverse of multiplication and divide both sides by 2 to get smaller number
ANSWER -> smaller number is 12 and 24 is larger number
Check : 12 + (12 + 12) = 36
