A math club has 40 people. the amount of boys is 5 less than 2 times the amount of girls. how many boys and girls are in the math club

The total number of students in the maths club is 40

the number of boys is 5 less than 2 times the amount of girls

to find the number of girls and boys let the number of girls be X.

so 2X-5 = the number of boy

so, X + 2X-5=40

3X-5=40

3X=40+5

3X=45

X=45/3

X=15

the number of girls is 15

and the number of boys is 15x2-5=25 boys
