Q. Simplify the expression:\newline7k−k+9k−10k7k - k + 9k - 10k
  1. Identify Like Terms: Identify like terms in the expression 7k−k+9k−10k7k - k + 9k - 10k. Like terms are terms that contain the same variable raised to the same power. In this expression, all terms are like terms because they all contain the variable kk raised to the first power.
  2. Combine Like Terms: Combine the like terms by adding or subtracting their coefficients.\newline7k−k+9k−10k7k - k + 9k - 10k can be simplified by combining the coefficients of kk.\newline(7−1+9−10)k(7 - 1 + 9 - 10)k\newline=(15−11)k= (15 - 11)k\newline=4k= 4k
