Q. Simplify the expression:\newline−7z−3z+4-7z - 3z + 4
  1. Identify Like Terms: Identify like terms in the expression −7z−3z+4-7z - 3z + 4.\newlineThe like terms here are −7z-7z and −3z-3z, which are both coefficients of zz.
  2. Combine Like Terms: Combine the like terms −7z-7z and −3z-3z.\newline−7z−3z=(−7−3)z-7z - 3z = (-7 - 3)z\newline=−10z= -10z
  3. Rewrite Simplified Expression: Rewrite the simplified expression with the combined like terms and the constant.\newlineThe simplified expression is −10z+4-10z + 4.
