You can simplify this by combining like terms on different sides:

7z - 9 = 3z + 19

7z - 3z = 19 + 9

4z = 28

z = 7

Answer: z = 7

Explanation:

To solve this equation,

First, you write the equation out

7z-9=3z+19

Then combine like terms:

7z - 3z = 19 + 9

4z = 28

Divide both sides of the equation by 4 to get the value of z

z = 28/4

Z = 7

I hope this helps.
