You can put this solution on YOUR website! if the sum of 2 numbers is is 39, the greater number is less than 5 than 3 times the smaller number, what are the 2 numbers ?
----------------------------------------------
Let x=the greater number
Let y=the smaller number
----------------------------------------------
1st.) We know that (x+y)=39
----------------------------------------------
2nd.) The greater number is going to be labeled as x.
Re-read statement looking for key words. The greater number (x) is(=) less than (subtraction) 5 than 3 times the smaller number (y).
So we have..
x=3y-5
----------------------------------------------
3rd.) Solve for y. Plug in what we found for x.
(x+y)=39
3y-5+y=39
4y-5=39
4y-5+5=39+5
4y=44
4y/4=44/4
y=11
----------------------------------------------
4th.) Solve for x. Plug in what we found for y.
(x+y)=39
x+11=39
x+11-11=39-11
x=28
----------------------------------------------
The two numbers are: x=28 and y=11
