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:
Divide both sides of the equation by 4 to get the value of z
z = 28/4
Z = 7
I hope this helps.
