You can put this solution on YOUR website! Hello,
We could set up two equations like this:
x+y=84
3x=y
Now subtract y from both sides in the second equation.
3x-y=0 Then add this equation to the other.
x+y=84
We get:
4x=84 Divide each side by 4 to get:
x=21 We now can find what y is equal to:
y=63
There we go.
