Answer:
The solution of the equation −4x−2y=−12 , 2x+4y=−12 are (6 , -6) .
Step-by-step explanation:
As given the equations are
−4x−2y = −12
Simplify the equation
-2(2x + y) = -12
2x + y = 6
Another equation
2x+4y=−12
2(x+2y) = −12
x + 2y = -6
Two equation becomes
2x + y = 6
x + 2y = -6
Multiply x + 2y = -6 by 2 and subtracted from 2x + y = 6 .
2x - 2x + y - 4y = 6 + 12
-3y = 18
[tex]y = \frac{-18}{3}[/tex]
y = -6
Putting the value of y in the equation
2x + -6 = 6
2x = 12
[tex]x = \frac{12}{2}[/tex]
x = 6
Therefore the solution of the equation −4x−2y=−12 , 2x+4y=−12 are (6 , -6) .
