Question

How many solutions does the equation 6z − 3z − 7 = −2 + 3 have?

Answer 1

Answer:

Equation have Unique solution with $z=2.67$

Step-by-step explanation:

Given Equation:

$6z - 3z - 7 = -2 + 3$

Solving the equation:

                   $6z-3z-7=1$

Adding 7 to both sides:

                      $6z-3z-7+7=1+7\\\\6z-3z=8\\\\3z=8\\\\z=8/3 \\\\or\\\\ z=2.67$

The Equation have Unique solution with $z=2.67$
