Step-by-step explanation:

Solve it by substitution. First let's rewrite the first equation (3x+4y=16) so we have y = something, then we'll substitue that in to the other equation.
3x+4y=16
4y=-3x+16
y=-3/4x+4
Now we can substitute this into the other equation.
You can try 4 x 6 = 24 so you can have 4 team mates of 6 groups ? is that what your asking
