Question

the sum of two no.s is 145 and the largest one of the two is less than double of the smaller by 50. find the numbers​

Answer 1

Answer:

Let the two unknown numbers be x and y

Let x > y

According to the question:

x + y = 145 --- i

x = 2y - 50 ---- ii

Rearranging ii

x - 2y = -50 --- iii

Subract iii - i

x - 2y = -50

-x - y = -145

=> -3y = -195

=> y = 65 -- iv

Substitute iv in i,

x + 65 = 145

x = 145 - 65

=> x = 80
