Answer:
24 and 9
Step-by-step explanation:
Hi there!
Let x be equal to the larger integer.
Let y be equal to the smaller integer.
<u>1) Construct equations</u>
(The sum of two integers is 33)
(The larger is 6 more than twice the smaller)
<u>2) Solve for one of the integer</u>
Isolate x in the first equation

Plug the first equation into the second

Combine like terms

Therefore, the smaller integer is 9.
<u />
<u>3) Solve for the other integer</u>

Plug in y (9)

Therefore, the larger integer is 24.
I hope this helps!
