In some​ country's congress, the number of representatives is 25 less than five times the number of senators. there are a total of 515 members. find the number of senators and the number of representatives.

Respuesta :

let number of senators = x, then:-

number of representatives = 5x - 25  so

x + 5x - 25 = 515
6x = 540
x = 90  
number of reps =  515 - 90 = 425

so there are 90 senators and 425 representatives.
