Mathematics
1 answer:

Answer:

9 and 6

Step-by-step explanation:

Write down the system.

The two numbers are x and y.

We are therefore given:

x+y=15

x-y=3

I will solve this for elimination since it is already setup for it.

I will add the columns since both equations are in the same form.

2x+0y=18

2x      =18

Divide both sides by 2:

x        =18/2

Simplify:

x        =9

So if x+y=15 and x=9, then y=6.

The two numbers are 9 and 6.

Test:

9+6=15

9-6=3

Which of the following is(are) the solution(s) to |5x+2|=8 ?
slega [8]

Answer:

x = 6/5 or x = -2

Step-by-step explanation:

We need to solve:

|5x+2|=8

We know that |u|=a the u = a and u = -a

Now solving:

|5x+2|=8

5x +2 = 8 or 5x +2 = -8

5x = 8-2 or 5x = -8-2

5x = 6 or 5x = -10

x = 6/5 or x = -10/5

x = 6/5 or x = -2

So, x = 6/5 or x = -2
