Explanation Given information: The sum of the digits of a two digit number is 12 and when the digits are reversed the number is decreased by 18. Formula used: Five-steps approach to solve a problem. 1. Familiarize with the provided information of the problem. 2. Write an equation by translating all the information problem into mathematical language. 3. Carry out the mathematical operation to solve the obtained equation. 4. Check the answer in the original situations provided in the problem. 5. Finally state the solution in a complete sentence. Calculation: To find the number use the five steps for problem solving. Consider the given information. 1. Familiarize: The sum of the digits of a two digit number is 12 and when the digits are reversed, the number is decreased by 18. Let x be the first digit and y be the second digit. The first number can be written as 10 y + x . Similarly the second number is obtained when the digits are replaced. Therefore x is on the tens place and y on the ones place and can be written as 10 x + y . 2. Translate: The first equation is, x + y = 12 The second equation is 10 x + y = ( 10 y + x ) − 18 Simplify the second equation further by collecting the like terms. 10 x + y = ( 10 y + x ) − 18 − 18 = 10 x − x + y − 10 y − 18 = 9 x − 9 y 2 = − x + y Thus two equations can be obtained. x + y = 12 …… (1) − x + y = 2 …… (2) 3. Carry Out To eliminate x add both the equations (1) and (2) and solve for y
