The Sum of Four Times a Number and Two is Fourteen

Apply the problem-solving strategy to find a number when "the sum of four times a number and two is fourteen". Let nn be the number. "Four times a number" translates to 4n4n. The "sum" of this and 22 is 4n+24n + 2. "Is fourteen" translates to =14= 14. This gives the equation 4n+2=144n + 2 = 14. To solve, subtract 22 from both sides to get 4n=124n = 12. Then divide by 44 to find n=3n = 3. Checking the answer: four times 33 is 1212, plus 22 is 1414. Thus, the number is 33.
