Which equation matches the statement: ‘A number increased by 6 equals 15’?

Explanation:
When you hear “a number increased by 6,” think of adding 6 to that number. If the result is 15, the unknown number plus 6 must equal 15. Using a variable for the unknown number, that equation is k + 6 = 15. This matches the statement exactly because you’re taking a number, increasing it by 6, and the total is 15. Solving it shows k = 9 (subtract 6 from both sides). The other forms would imply different operations or different results, not the idea of adding 6 to the number to get 15.
