Suppose you want to solve the equation 2a + b = 2a, where a and b are nonzero real numbers. describe the solution to this equation. justify your description.

Answer and explanation:

In this problem, we have the following equation:

And the problem states that and are nonzero real numbers. First of all, we need to assume that and are nonzero real numbers. Thus, let's say that:

Plug in the equation, we have:

As you can see, we got an absurd statement since . Then, the only possible solution is that . So, we can write our equation as follows:

Conclusion:

For any real number , we will have that

If there are four friends then each would get, 1.25 or 1 1/4. so this is how i solved 5 ÷ 4 = 1.25 . hope this ; )

The answer is: y would equal 3 because if you simplify the equation then it would be y= 3x+9 and if you divide 3x and 9 by 3 it would equal 3. y= 3
