Hello I have another word problem (yuckkkk) Please help. A group has equal number of male and female. If 12 more males join the group and 7 females leave the group, then there will be 2 times more males than females.

    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?

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