Answer:

the answer is C. That is 9 and 33.

Step-by-step explanation:

x = 4y - 3

x + y = 42

where x and y are the two integers. we are going to replace the variable x with this value in the second equation.

(4y - 3) + y = 42

Now, let's combine like terms in the equation.

5y - 3 = 42

add 3 to both sides of the equation to get the variable y

5y = 45

y = 9

let's substitute this value back into the second equation.

x + (9) = 42

Let's subtract 9 from both sides of the equation to get the variable x alone.

x = 33

Thus, the answer to your question is C. 9, 33 because y = 9 and x = 33 in our equations.
