Question

The sum of 2 numbers is 10 and their difference is 4

Answer 1

Answer:

7 and 3

Step-by-step explanation:

Let the numbers be x and y

x + y = 10

x - y = 4

Adding both the equations we get

x + y + x - y = 10 + 4

2x = 14

x = 7

Now, x + y = 10

so y = 10 - x

y = 3

Therefore the numbers are 7 and 3

Answer 2

Answer:

• 7 and 3

Step-by-step explanation:

Given

• Sum of 2 numbers = 10
• Difference of two numbers = 4

To find

• The 2 numbers.

Solution

Let the numbers be x and y.

Then, accordingly we get :

• x + y = 10 - (i)
• x - y = 4 - (ii)
• 2x = 14
• x = 14/2
• x = 7

Substitute x in (i),

• x + y = 10
• 7 + y = 10
• y = 10 - 7
• y = 3

∴ The 2 numbers are 7 and 3.
