You can put this solution on YOUR website! Adult x Numbers
Child ------------ y Numbers
x+y=600 .............1
20x+10y=9800 .............2
Eliminate y
multiply (1)by -10
Multiply (2) by 1
-10x-10y=-6000
20x+10y=9800
Add the two equations
10x= 3800
/10
x=380
plug value of x in (1)
x+y=600
380+y=600
y=600 -380
y=220
