Equality Properties

Algebra I

Step-by-step explanation:

Step 1: Define

Identify

Let x be one number and y be the other.

x + y = 4

x - y = 6

Step 2: Solve for x

Elimination

Step 3: Solve for y

5 and -1

Step-by-step explanation:

Let the two numbers be x and y

x+y =4

x-y = 6

Add the two equations together

x+y =4

x-y = 6

2x = 10

Divide by 2

2x/2 =10/2

x=5

x+y = 4

5+y = 4

y = 4-5

y = -1

The numbers are 5 and -1

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

the answer is two. hope this !
