Question

the sum of two number is 80 the greater number exceeds another number by 11 find the number​

Answer 1

Answer:34.5 and 45.5

Step-by-step explanation:

Let a and b be the numbers

Then a+b=80—-(1)

and a-b=11——(2)

(1)+(2)—>

2a=91

a=45.5

(1)-(2)—->

2b=69

b=34.5

Answer 2

Step-by-step explanation:

Let the smaller number be x

Then the bigger will be 11 + 2x

A/q,

=> 11 + 2x + x = 80

=> 3x = 80-11

=> x = 69

=> x = 23 ans.

And, also 11 + 2x = 11 + 46 = 57 ans.
