Q. Find the value of each variable. \newline127+z=300127+z=300
  1. Subtract 127127 to isolate zz: Subtract 127127 from both sides to isolate zz.\newlineCalculation: 300−127=173300 - 127 = 173
  2. Check solution with substitution: Check the solution by substituting z=173z = 173 back into the original equation.\newlineCalculation: 127+173=300127 + 173 = 300
