5\times 10=4N
Multiply both sides of the equation by 40, the least common multiple of 8,10.
50=4N
Multiply 5 and 10 to get 50.
4N=50
Swap sides so that all variable terms are on the left hand side.
N=\frac{50}{4}
Divide both sides by 4.
N=\frac{25}{2}
Reduce the fraction \frac{50}{4} to lowest terms by extracting and canceling out 2.
