Answer :
two numbers equal 21
x+y=21
x<y
3y=4x
y=4x/3
x+4x/3=21
7/3x=21
7x=63
x=9
9+y=21
y=12
x+y=21
x<y
3y=4x
y=4x/3
x+4x/3=21
7/3x=21
7x=63
x=9
9+y=21
y=12
[tex]x,y-\ two\ numbers\ , x-\ smaller\\\\
x+y=21\ \ \ \ | x=21-y\\
3y=4x\\\\
3y=4(21-y)\\\\
3y=84-4y\ \ \ | add\ 4y\\\\
7y=84\ \ \ \ | divide\ by\ 7\\\\
y=12\\\\
x=21-12=9\\\\ Smaller\ number:\ 9\\\\ Larger \ number:\ 12[/tex]
