Answer:
(x,y) = (-1,1)
Step-by-step explanation:
Given the equations
y = 2x + 3 
x - y = -2
substitute the value of y in the first equation into the second
x - (2x + 3) = -2
x -2x - 3 = -2
-x - 3 = -2
add 3 to both sides
-x = -2 + 3
- x = 1
Divide both sides by -1
x = -1
Substitute into the first equation
y = 2(-1) + 3
y = -2 + 3
y = 1
 
        
             
        
        
        
Answer:
The salary after four consecutive increase = $ 46794.34 
Step-by-step explanation:
According to question, 
salary of MR. John = $ 40000 per year
percentage py increase = 4%
Let the salary after four consecutive pay increase = x
So, X = 40000 (1 + )^4
)^4
Or, X = 40000 ( )^4
)^4
Or, X = 46794.34
Hence the salary increase after four consecutive pay increase at 4% = $46794.34  Answer
