Quizplus · Accepted Answer

Let the smaller integer be x. Then the larger integer is x + 1. The equation is 3x + 4(x + 1) = 144. Simplifying gives 3x + 4x + 4 = 144, which simplifies to 7x + 4 = 144. Subtracting 4 from both sides gives 7x = 140. Dividing both sides by 7 gives x = 20. Thus, the smaller integer is 20.
