Question

Solve for x.
4/7x=2/7

A.x = 8/49
B.x = 1/2
C.x = 2
D. x = 4

Answer 1

Hi there!

To solve for X is fairly simple, since there's only one step to it.
That step is to multiply both sides of the = by 7/4.

(7/4) * (4/7x) = (7/4) * (2/7)

Using a calculator also helps, but we ended up with x = 1/2.
So, the correct answer to this equation would be answer choice B.

I hope this helped you! :)

Answer 2

So all you gotta do is multiply the reciprocal of 4/7, aka 7/4, on each side.


`(7)/(4) * (4)/(7) x= (2)/(7) * (7)/(4) \\ \\ x= (14)/(28) = (1)/(2)`

The answer is B.
