The sum of two integers is 75. The second number is three less than twice the first

x = 26, y = 49

Step-by-step explanation:

Let the two numbers be x and y. We can use these two variables to form to equations, which we can then solve.

x + y = 75 (the sum equals the numbers added) (duh)

and

y = 2x - 3 (the second number, y, equals twice, or 2 * the first number, x, minus three. We could also rephrase this as y - 2x = -3)

Now, we can solve this a few different ways. Let's use substitution:

x + y = 75

y = 2x - 3

x + (2x - 3) = 75

x + 2x - 3 = 75

3x - 3 = 75

3x = 78

x = 78/3

x = 26

From here we can solve for y:

x + y = 75

75 - x = y

75 - 26 = y

y = 49
