Answer:
[tex]6x-6y=30[/tex]
Step-by-step explanation:
The complete options are
a) x - 2y = 30
b) 4x - 3y = 30
c) 3x - 4y = 30
d) 6x - 6y = 30
The given equation is
[tex]x-y=5[/tex]
Verify option d
we have
[tex]6x-6y=30[/tex]
Divide by 6 both sides
[tex](6x-6y)/6=30/6[/tex]
[tex]\frac{6x}{6}-\frac{6y}{6}=\frac{30}{6}[/tex]
[tex]x-y=5[/tex]
therefore
[tex]x-y=5[/tex] and [tex]6x-6y=30[/tex] are equivalent
