Final Answer
Thank you for the opportunity to help you with your question!
5z+7z=48
we can factorize z since it is common on the left side of the equation;
z(5+7)=48
z(12)=48
dividing both sides by 12,
z=48/12
z=4
Please let me know if you need any clarification. I'm always happy to answer your questions.
