Answer:
x - y = -9
Step-by-step explanation:
from the equation
3y - x = 3
and x is four times the value of y
i.e x = 4y
put x = 4y into the first equation
we have;
3y - 4Y = 3
-Y = 3
Divide both sides by -1
we have
y = -3
so put y = -3 in the 2nd equation
i.e x = 4y
x = 4 × -3
x = -12
therefore x = -12 and y = -3
so tho find x - y
we have
-12 - (-3)
= -9
therefore x - y = -9
Answer:
Step-by-step explanation:
m = 5 + 10d
The variable "d" is the independent variable because its value does not depend on another variable. The variable "m" is the dependent variable because its value depends on the value of the variable "d"
