Answer:
2x + 4y = 4
-8x + 8y = -16.
Step-by-step explanation:
We can find an equivalent system by multiply the 2 equations by 2.
x + 2y = 2 multiplied by 2 is 2x + 4y = 4.
Answer:
[tex]x=2, y=0[/tex]
Step-by-step explanation:
Given Equations:
[tex]x + 2y = 2[/tex] Equations:1
[tex]-4x + 4y = -8[/tex] Equation:2
Multiplying equation:1 by '2'
[tex]2x + 4y = 4[/tex] Equation:3
Using Elimination Method, Subtracting Equation:2 from Equation:3
[tex]2x+4y-(-4x + 4y) = 4-(-8)[/tex]
[tex]2x+4y+4x - 4y = 4+8\\6x=12\\x=\frac{12}{6} \\x=2[/tex]
Putting the value of 'x' in Equation:1
[tex]x + 2y = 2[/tex]
[tex]2 + 2y = 2\\2y=2-2\\2y=0\\y=0[/tex]
The value of 'x' is 2
The value of 'y' is 0
