If we divide the number of novelists by the number of poets, the quotient is always equal to 53.
Novelists: 15
Poets: 9
there are 24 people at the workshop.This implies that the sum of the number of novelists and the number of poets equals 24. n+p=24 The two equations written above form a system of equations that models the described situation. 3n-5p=0 & (I) n+p=24 & (II) We can solve this system using the Elimination Method. To do that, first we need to multiply Equation (II) by 5. That way, when we add the equations, the p-terms will cancel each other out. 3n-5p=0 5(n+p)=5(24) ⇒ 3n-5p=0 5n+5p=120 With this, we can see that the p-terms will eliminate each other if we add Equation (I) to Equation (II).
(II): Add (I)
(II): Add and subtract terms
(II): .LHS /8.=.RHS /8.
