X = boys
2x+24=5x
Subtract 2 x from each side
24=3x
X=24/3 = 8
there are 8 boys
Answer:
8 boys are in the group
Step-by-step explanation:
A group consisted of 2 girls for every boy. 24 more girls joined the group. There are now 5 girls for every boy.
Let 'x' be the number of boys
2 girls for every boy and 24 more girls joined
So number of girls now = 2(number of boys ) + 24
2x + 24
now 5 girls for every boy.
number of girls now = 5 (number of boys)
5x
2x + 24 = 5x
Subtract 2x on both sides
24 = 3x
Divide by 3 on both sides
x= 8
So number of boys in the group = 8
