Question

sum of two numbers is 17 and their differences is 3.Find the two numbers by forming 2 equations and solving them simultaneously​

Answer 1

Answer:

The numbers are 10 & 7.

Step-by-step explanation:

Let the numbers be X and Y.

A.T.Q:

X + Y = 17

X - Y = 3

Solving the equations,

(X + Y)+(X - Y) = 17+3

=> 2X = 20

=> X = 10.

Now, 10 + Y = 17

=> Y = 7.

Answer 2

Answer:

a=10 b=7

Step-by-step explanation:

let a and b be two numbers

a+b=17    eq.1

a-b=3     eq.2

eq.2-eq.1

=a+b-(a-b)=17-3

=a+b-a+b=14

=2b=14

b=14/2=7

b=7

a-b=3

a-7=3

a=7+3

a=10
