Hey there :)
Let us translate the words into mathematics!
The difference of 2 numbers is 3
x - y = 3
The sum of 2 numbers is 13
x + y = 13
(eq. 1) x - y = 3
(eq.2) x + y = 13
eq. 1 + eq.2 ⇒ x - y = 3
+ x + y = 13 ( -y and +y cancels out )
2x = 16

x = 8
We have the value of x, simply substitute it in either of the formulae to find y
x - y = 3 , 8 - y = 3 , 8 - 3 = y , 5 = y
x + y = 13 , 13 - 8 = y , 5 = y
x = 8 , y = 5

Answer:
(-1, 9) (he x value is placed first).
Step-by-step explanation:
y = -3x + 6
y = 9
Substitute y = 9 into the first equation:
9 = -3(x) + 6
-3x = 9 - 6
-3x = 3
x = -1.
