The sum of three different numbers is 67. The two larger numbers differ by 7 and the two smaller numbers differ by 3. What is the value of the largest number?
Let the middle number be x. The sum of the 3 numbers will be 3x+4. Write the following equation : 3x+4 = 67 Thus, 3x = 63, And x = 21 Thus, the largest number is 28 (21+7)
