This problem is solved by creating an equation.
We assign x to the number of girls on the team.
We assign x+6 to the number of boys on the team since there are 6 more boys than girls.
16=x+x+6
We combine like terms to get
16=2x+6
Then we solve by subtracting 6 from both sides.
16-6=2x+6-6
To get:
10=2x
finally we isolate x by dividing both sides by 2
Result
5=x
There are 5 girls on the team.
And 5+6=11 makes 11 boys.
