X=number of boys in the club at first
y=number of girls in the club at first.
(x+y) = members were in the club at first.
We can suggest the next system of equation.
x/y=1/2 ⇒ x=y/2
(x+5)/y=3/4 ⇒4(x+5)=3y
Finally, we have the next system of equations:
x=y/2
4(x+5)=3y
We are going to solve by substitution method.
4(y/2 + 5)=3y
2y+20=3y
2y-3y=-20
-y=-20
y=20
x=y/2
x=20/2
x=10
(x+y)=10+20=30
Answer: There were 30 members int the club at first, they were 10 boys and 20 girls.
In order to solve this equation that has variables on both sides, you should try to move either one constant term to the other side or one term with a variable to the other side first. Let's add -11x to both sides of the equation (we are carrying out the addition property of equality). Now, you should move a term from the side with more terms to the other side. Let's add 12 to both sides of the equation, so -12+12 will cancel out and equal 0, while 6+12 will equal 18. Finally, divide both sides of the equation by the coefficient of the variable, which is 18. This allows us to isolate the variable. Now, you should have your answer, which is 18/18 (you simplify this :) ) .
