Answer:C
Step-by-step explanation:4x _2y =64 because 8×8= 64
For this case we must find an equation equivalent to:
[tex]\frac {1} {4} x- \frac {1} {2} y = 8[/tex]
We add [tex]\frac {1} {2}[/tex] and on both sides of the equation:
[tex]\frac {1} {4} x = 8 + \frac {1} {2}y[/tex]
We multiply by 4 on both sides of the equation:
[tex]x = 32 + \frac {4} {2}y\\x = 32 + 2y[/tex]
Multiplying by 2 on both sides of the equation:
[tex]2x = 64 + 4y\\2x-4y = 64[/tex]
