Final answer:
To solve the equation (3z + 1) + (5 + 7z), combine the like terms. The solution is 10z + 6.
Step-by-step explanation:
To solve the equation (3z + 1) + (5 + 7z), we combine like terms. This means adding the coefficients of the z terms and adding the constants. So, we have 3z + 7z + 1 + 5. Combining like terms, we get 10z + 6.
The solution to the equation is 10z + 6.
