y=15

Explanation:

9/6=y/10

Reduce the left term by factorising and cancelling the common terms in the numerator and denominator.

(3xx3)/(3xx2)=y/10

(cancel3xx3)/(cancel3xx2)=y/10

3/2=y/10

Multiply both sides by 10.

10xx3/2=10xxy/10

Reduce the terms by factorising and cancelling the common terms.

2xx5xx3/2=cancel10xxy/(cancel10)

cancel2xx5xx3/(cancel2)=y

5xx3=y

15=y
