    Form a venn diagram and write the following equation:
Girls playing only netball + only hockey + both + neither =30.
Let girls playing both be x.
Hence, (18-x) + (14-x) + x + 5 =30.
Solve for x.
Answer is 7

    18-x+14-x+x+5=30
18+14+5+x+x-x=30
37+x=30
37-30=x
X=7
    
18+14+5+x+x-x=30
37+x=30
37-30=x
X=7
