1. Divide the numbers 1st
4/6=10/x
2/3=10/x
2. Eliminate the fraction denominators
2/3=10/x
x•2/3=x•10/x
3. Simplify
x•2/3=x•10/x
2/3x=x•10/x
2/3x=10
4. Eliminate fraction denominators
2/3x=10
3•2/3x=3•10
5. Simplify
3•2/3x=3•10
2x=3•10
2x=30
6. Divide both sides of the equation by the same factor
2x=30
2x/2=30/2
X=30/2
X=15
