Question

A sum of two numbers is 70. Their difference is 30. Find the numbers

Answer 1

Answer:

Let the two numbers be x and y

X+y = 70...............(given)

X-y=30..................(given)

Adding both the above equations we get

2x=100

Therefore x=50

Substitite the value of X in equation 1

We get

Y=20

The two numbers are x=50

And y=20

Answer 2

Answer:

Here is ur answer

Step-by-step explanation:

Let the numbers be X and Y

A/Q

X+Y=70

=Y=70-X.... (equation 1)

Again

X-Y=30

putting the equation 1,we have

X-(70-X)=30

=X-70+X=30

=2X=30+70

=2X=100

=X=100/2

=X=50

X=50

Y=(70-X)

=70-50=20
