Answer:
(-4,5)
*View attached graph*
Step-by-step explanation:
y = -2x - 3
4y + x = 16
4y + x = 16
4(-2x - 3) + x = 16
-8x - 12 + x = 16
-7x - 12 = 16
+12 + 12
-7x = 28
/-7 /-7
x = -4
4y + x = 16
4y + (-4) = 16
4y - 4 = 16
+ 4 + 4
4y = 20
/4 /4
y = 5
(x,y) -> (-4,5)

Answer:
875
Step-by-step explanation:
As given, there is a three digit number
So, let assume three digit number be `xyz`.
Now, as given tens digit is 2 greater than the unit digit.
∴
Next, the hundred digit one greater than the tens digit.
∴
The sum of the tens and the hundreds digits is three times the units digit.
∴
Now, substituting the value in the equation.
⇒
solving it to get value of y
⇒
⇒
∴
Next, finding value of z
y=
substituting the value of y and subtracting both side by 2
∴ z=
Last, finding the value of x
substituting the value of y
∴ x= 8
xyz= 875
