Two digit-
igor_vitrenko [27]

Let the number = 10x+y

x+y = 9

y-x = 1

(x+y)+(y-x) = 9+1

2y = 10

y = 10/2

<h3><u>y = 5</u></h3>

x+y = 9

9-y = x

x = 9 - 5

<h3><u>x = 4</u></h3>

<h2>So, your number is <u>45</u></h2>

HELP PLEASE I WILL GIVE BRAINLIEST AND 35 POINTS!!!!!!!!!!!!!!!!!!!!!!!Which statements are true about the ordered pair (−1, 5)
murzikaleks [220]
The ordered pair (-1,5) is a solution to the system because it makes both equations true.

1) x+y=4
2) x-y=-6

1) -1 + 5 = 4
    5-1 = 4   you can switch the order to make it easier to understand
        so
        4 = 4

2) -1 - 5 = -6
     -1 + -5 = -6 you can change the sign in the middle and make y - 
          so
        -6 = -6
