Final answer:
A Computer Algebra System (CAS) can be used to solve and check solutions for equations. Here's how you can use a CAS to solve, apply opposite operations, and check each solution for the given equations.
Step-by-step explanation:
A Computer Algebra System (CAS) can be used to solve and check solutions for equations.
Here's how you can use a CAS to solve, apply opposite operations, and check each solution for the given equations:
A) To solve the equation a + 3 = 5 using a CAS, you can input the equation into the software and it will give you the value of a as 2.
B) For the equation a - 6 = 7, the CAS will determine that the value of a is 13.
C) Using the CAS with the equation 3m + 5 = 11 will result in m being equal to 2.
D) Lastly, the CAS will solve the equation -4b + 3 = -1 and find that b is equal to 1.
After solving using the CAS, you can apply the opposite operations to check the solutions.
For example, for equation A, if we substitute the value of a (2) back into the equation, we get 2 + 3 = 5, which holds true.
Similarly, you can apply the opposite operations and check the solutions for the other equations.
