If (4x-y,x-4y):(3,-3y) then find the value of x and y? please help me!
1 answer:
Answer:
- x=1
- y=1
Step-by-step explanation:
This looks like it is intended to represent two equations. They can be solved as a system in any of the usual ways.
The two equations seem to be ...
- 4x -y = 3
- x -4y = -3y
Adding 4y to the second equation gives ...
x -4y +4y = -3y +4y
x = y . . . . . . . . simplify
Substituting for y in the first equation gives ...
4x -x = 3
3x = 3 . . . . simplify
x = 1 . . . . . divide by 3
y = 1 . . . . . same as x
The variables x and y both have a value of 1.
