Systole and Diastole are 2 phases of the cardiac cycle. Systole is when the heart contracts to pump blood out. Diastole is when the heart relaxes after contraction and refills with blood.
(3/8)*n = -1/4 // + -1/4
(3/8)*n-(-1/4) = 0
(3/8)*n+1/4 = 0
3/8*n+1/4 = 0 // - 1/4
3/8*n = -1/4 // : 3/8
n = -1/4/3/8
n = -2/3
n = -2/3
