Answer:
Equation have Unique solution with [tex]z=2.67[/tex]
Step-by-step explanation:
Given Equation:
[tex]6z - 3z - 7 = -2 + 3[/tex]
Solving the equation:
[tex]6z-3z-7=1[/tex]
Adding 7 to both sides:
[tex]6z-3z-7+7=1+7\\\\6z-3z=8\\\\3z=8\\\\z=8/3 \\\\or\\\\ z=2.67[/tex]
The Equation have Unique solution with [tex]z=2.67[/tex]
