3y-x=3 and x is four times the value of y what is the value of x-y?
1 answer:
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
