63x+45x = 108x
You just multiply 3x by 21 and 15 to get 63x and 45x. You then add the like terms to get 108x.
Answer:

Answer 1 (edge correct answer):
One correct answer is that a systems engineer might work in air traffic control designing an air traffic control solution program. The program may be used to train thousands of air traffic controllers to ensure they can perform their jobs effectively.
Answer 2 (answer I made myself)
Explain why a systems engineer would work for the Federal Aviation Administration and describe his or her role.
A systems engineer would work for the Federal Aviation Administration because systems engineers are able to develop systems that manage the many technological systems that are on modern ships, planes, helicopters, etc. A systems engineer's role would be to design requirements, gather data, and develop systems for the project they are working on. Systems engineers are almost always required in projects made by the Federal Aviation Administration. The reason I believe that systems engineers are required in the FAA is because: "In an information technology field, an engineer may work to develop systems in virtually any industry. Health care, education, financial services, and transportation industries need information technology developers, managers, and engineers. In the transportation field, a systems engineer might work in air traffic control for a company that works for the Federal Aviation Administration. A systems engineer would help develop an air traffic control solution program. The program may be used to train thousands of air traffic controllers to be sure they can perform their jobs effectively." This evidence shows how the role as systems engineer has relates to joining with the FAA (Federal Aviation Administration).
Answer:
step 1 multiply the parentheses
63 - (63)
step 2 subtract
63 - 63= 0
