Answer:
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
