Question

the sum of two number is 90 and the greater number exceeds twice the smaller number by 15 find the numbers

Answer 1

The numbers are 65 and 25.

Answer 2

Let the numbers be x and y.

Let x be greater than y.

x - 2y = 15......eqn 1

x + y = 90...... eqn 2

eqn (1)-(2)


x - 2y - x - y = 15 - 90

-3y = -75

y = 25

Put value of y in any equation

x + 25 = 90

x = 65

So your numbers are 65 and 25.

Thank you.
