Solve for x: -4x=2x+5

x= or 0.83

Step-by-step explanation:

-4x=2x+5

First, you subtract 2x from both sides

-4x - 2x = 2x - 2x + 5

-6x = 5

Divide both sides by the coefficient of x(The coefficient of x here is -6)

x =

OR

In decimal form⇒ 0.82828282...

                         ≅ 0.83

∴ x = or 0.83

Hope this helps!!!

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
