Full solution

Q. Solve for zz.\newlinez+4<7z + 4 < 7
  1. Identify Operation for Isolation: Identify the operation needed to isolate zz. Since 44 is being added to zz in the inequality z + 4 < 7, we should use subtraction to isolate zz.
  2. Subtract 44 to Solve: Subtract 44 from both sides of the inequality to solve for zz.z + 4 - 4 < 7 - 4This simplifies to z < 3.
