The sum of two numbers is 0. Twice the smaller number subtracted from 3 times the larger number is 10. Let x represent the large
Bezzdna [24]

Answer:

x+y=0 and 3x-2y=10

Step-by-step explanation

Let the numbers be x and y.

The sum of the two numbers is 0

\implies \: x + y =0

Letting the smaller number be y and the

larger number be x:

twice the smaller number

\implies \: 2y

Also, 3 times the larger number

\implies \: 3x

Now ,twice the smaller number subtracted from 3 times the larger number is 10.

\implies \: 3x - 2y = 10

Therefore the equations are

x + y =0

and

3x  - 2y =10

44.6
