The sum of two numbers is 40. the second number is 5 less than twice the first number. let x represent the first number and let y represent the second number. what is the value of the first number? use the table to guess and check. 15 20 25 30

Step-by-step explanation:

The sum of two number is 40 would be:

The second number is 5 less than twice the first number would be:

Now, we can find the value by solving this system of equations, we will isolate x in the first equation, then we replace it in the second equation:

Then, we replace this value in one equation of find the other variable:

Therefore, the value of the first number is 15 and the second number is 25.

w'x is 0.
