Let's call the first unknown integer x and the second one y.

"Four times an unknown integer"

  • We can write it as 4x

"Multiplied by three times the unknown integer plus a different unknown integer"

  • 4x is multiplied by 3x+y, so 4x(3x+y)=12x²+4xy

"Equals 100."

  • 12x²+4xy=100

And so the answer is C: 12x²+4xy-100=0
