The sum of two numbers is 8 and the difference is 2

2

x+x=8-2

2x=4

Divide:

4/2=2

x=2

5 and 3

Step-by-step explanation:

From the question,

Let the first number be x

And the second be y

x + y= 8

x- y= 2

Add the equations

x + y + x - y = 8 + 2

2x= 10

x=5

Slot the value of x into any of the equations: x +y = 8

5+ y= 8

y= 8 - 5

y = 3

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
