The sum of two numbers is zero. when 15 times the smaller numbers is added to 10 times the larger, the result is 1. find the two numbers.

We have two numbers say a, b. And a system of equations.

It looks a bit intimidating but it's actually very easy.

Instead of term a + b in the second equation we can say it's zero because the first equation describes a + b as being equal to 0.

So,

The above equation is not true therefore numbers a and b do not exists in the real number domain.

No solution.

Hope this helps.

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9

4

step-by-step explanation:

6 (donuts) divided by 3 is 2.
