-x + y = 4
2x + y = 1
-3x = 3
-3 -3
x = -1
2x + y = 1
2(-1) + y = 1
-2 + y = 1
+ 2 + 2
y = 3
(x, y) = (-1,3)
100/100 ---> 50/50 ---------> 25/25 -----------> 5/5
Answer:
Yes, k = 1/3 and y = 1/3x
Step-by-step explanation:

The equation would be ⇒ 
The operation which you should do first in the Simplification of the expression -3(-5) - 16 is -3 times -5. option A
Simplification
Based on the principle of BODMAS
B = Bracket
O = of
D = Division
M = Multiplication
A = Addition
S = Subtraction
-3(-5) - 16
open parenthesis
= 15 - 16
= -1
