Find the value of two numbers if their sum is 12 and their difference is 4.

Step-by-step explanation:

Equation 1: Sum:

x + y = 12

Equation 2: Difference:

x - y = 4

Solution:

x + y = 12

x  - y =   4

Add the two equations together:

2x = 16

Divide both sides by 2:

x = 8

Solve for y:

Use equation 1 substituting for x:

x + y = 12

8 + y = 12

Subtract 8 from both sides:

y = 4

one number is 8 and the other number is 4.

8 + 4 = 12

8 - 4  =  4
