Answer: 25 and 22
Step-by-step explanation:
Since one number is 3 bigger than the other, we can call them x, and x-3.
Then we know that the sum of 3 times x and 2 times (x-3) is equal to 19, so we can make the equation
3x+2(x-3)=19
Simplifying would get you
3x+2x-6=19
adding the x's and adding six to both sides of the equations gets you
5x = 25
divide by 5 and
x=5
Put those numbers back into your previous labels for them, x and x-3, and you get 5 and 2
