Question

the sum of two numbers is 8 and their difference is 4 find the numbers​

Answer 1

Answer:

6 and 2

Step-by-step explanation:

Steps are as follow:

1. Define one of the terms

2. Define the relationship of the second term relative to the first term

3. Solve the unknown

4. Find the numbers

STEP 1: Define the first term:

Let x be one of the number

STEP 2: Define the relationship of the second term:

Since the sum of the two number is 8

The other number is 8 - x

STEP 3: Solve the unknown:

Given that the difference is 4

x - (8 - x ) = 4

/* remove the bracket */

x - 8 + x = 4

/* combine like terms */

2x - 8 = 4

/* add 8 to both sides */

2x = 12

/* Divide both sides by 2 */

x = 6

STEP 4: Find the numbers:

One of the number is x, therefore 6

The other number is 8 - x, therefore 8 - 6 = 2

Answer: The number is 6 and 2

Answer 2

6+2=8

6-2=4

so number is 62
