Question

the two sum do two numbers is 90 and the greater number exceeds twice the smaller by 15. find the number
​

Answer 1

Step-by-step explanation:

let x be greater no

y be smaller no

according to first condition

x + y = 90

according to second condition

x = 2y + 15

x - 2y = 15

subtracting 1 and 2 condition

x + y = 90

- x - 2y = 15

3y = 105

y = 35

put y in 1

x + 35 = 90

x = 55
