Exercise 38 Page 85

How can you isolate z on one side?

z=28

Practice makes perfect
To solve the equation, we have to isolate z on one side. By multiplying both sides of the equation by 2, we can eliminate the denominator and isolate z.
14=z/2
14* 2=z/2* 2
14* 2=z
28=z
z=28
We can check the solution by substituting it into the equation and simplifying.
14=z/2
14? =28/2
14=14
Since z=28 satisfies the equation, we have found the correct solution.
