Using simple linear equation with one unknown.

ash2326 · Answer

Let initially the no. of males= no. of females be "x"
If 12 more males join the group and 7 females leave the group,
no. of males now= (x+12) 
no. of females now= (x-7)
Do you get this part?

anonymous · Answer

yes I got that part

ash2326 · Answer

then there will be 2 times more males than females.  
so
x+12=2(x-7)
Can you solve this for x?

anonymous · Answer

my first though was x+12+x-7=3x
