Solve for x: 2 over 5 (x - 4) = 2x.

A. -8

B. negative 1 over 2

C. 1

D. -1

Answer 1

Well you can plug in your answer choices as x, and then solve your equation. If both sides are not equal, then that is not your answer

Answer 2

One way of doing it.

Answer 3

I'll get you started

\[\Large \frac{2}{5}(x - 4) = 2x\]

\[\Large 5*\frac{2}{5}(x - 4) = 5*2x\]

\[\Large 2(x - 4) = 10x\]

\[\Large 2x - 8 = 10x\]

and let you take over from here

Answer 4

8x = 8?

Answer 5

close but no

Answer 6

I am not really in the thinking mood ; _ ; nor helping mood D: I hate it when I am like that

Answer 7

so its C???

Answer 8

that's fine sammixboo

it should be

2x - 8 = 10x

-8 = 10x - 2x

-8 = 8x

x = ???

Answer 9

?

Answer 10

D?

Answer 11

you mean x = -1 right?

Answer 12

lol yeah XD im so tirededefian9fjashfeqfj9q8uhr3

Answer 13

yep correct

Answer 14

Check:

\[\Large \frac{2}{5}(x - 4) = 2x\]

\[\Large \frac{2}{5}(-1 - 4) = 2(-1)\]

\[\Large \frac{2}{5}(-5) = 2(-1)\]

\[\Large -2 = -2\]

so that verifies the solution
