~You would set up the equation x+(3x+5)=6565 ~Combine like products so 3x+x=4x. ~Now you have 4x+5=6565. ~Isolate the variable by subracting the 5 from both sides, so you have 4x=6560. ~Since you multiply x by 4, divide both sides by 4, and 6560 divided by 4 is 1,640. *The first number is 1,640. ~Now to find the second number you simply plug in 1,640 to (3x+5), with 1,640 being x. ~That would become [3(1,640)+5]. ~3 times 1, 640 is 4,920, and add the 5 so you get 4,925. *The second and larger number is 4,925. If you wanna check just add the two numbers, and you get 6565.
