Answer:
(-2, 4)
Step-by-step explanation:
y = -3x - 2
y = -x +2
=> -3x - 2 = -x +2
     -3x + x = 2 + 2
     -2x = 4
         x = -2
      -x + 2 = y
       2 + 2 = y
             4 = y

positive integer
Step-by-step explanation:
In a bank account,
A paid out expense is called as debit
A deposit is called as credit
To find: sign used to represent credits
Solution:
Integers denote a set of natural numbers, their negative counterpart, and 0.
As credit denotes the amount deposited, the positive integer is used to denote credits.

Answer:
The perimeter of a rectangle is the sum of both lengths and both widths, which is equal to 54 meters. Let's call Length L and Width W. 
 
The question is saying this: L = 3 meters + 3(W). We have 2 variables, which means we need at least 2 equations to solve. So far we have one, our second equation is from the perimeter. 
 
2 lengths + 2 Widths = 54. Now, it's just a plug and chug.
 
2(3 + 3W) + 2W = 54.
 
6 + 6W + 2W = 54
 
8W = 48
W=6
L = 3 + 3(6) = 21
To double check: 2(21) + 2(6) = 42 + 12 = 54
 
The Width is 6 meters, and the Length is 21 meters.
