Full solution

Q. Combine the like terms to create an equivalent expression.\newline7kk+19=07k-k+19=\boxed{\phantom{0}}
  1. Identify like terms: Identify like terms in the expression 7kk+197k - k + 19.\newlineLike terms are terms that contain the same variable raised to the same power. Here, 7k7k and k-k are like terms, while 1919 is a constant term.
  2. Combine like terms: Combine the like terms 7k7k and k-k.\newlineTo combine them, we add their coefficients: 71=67 - 1 = 6.\newlineSo, 7kk7k - k becomes 6k6k.
  3. Rewrite expression: Rewrite the expression with the combined like terms.\newlineThe expression now is 6k+196k + 19.
  4. Check for other like terms: Check for any other like terms that can be combined.\newlineThere are no other like terms in the expression 6k+196k + 19.
