To solve the equation for z, we can simplify both sides of the equation first.
On the left side, we have 7z + 3z = 10z.
On the right side, we have 9z - 4.
Now we can rewrite the equation as:
10z = 9z - 4.
To isolate z, we can subtract 9z from both sides:
10z - 9z = 9z - 9z - 4.
This simplifies to:
z = -4.
Therefore, z equals -4.
On the left side, we have 7z + 3z = 10z.
On the right side, we have 9z - 4.
Now we can rewrite the equation as:
10z = 9z - 4.
To isolate z, we can subtract 9z from both sides:
10z - 9z = 9z - 9z - 4.
This simplifies to:
z = -4.
Therefore, z equals -4.
