Given the equation 2x + 4 = 4x - 2, select the reasoning that correctly solves for x. 1) Add 2, subtract 2x, then divide by 2.

2) Add 2, subtract 4x, then divide by -2.

3) Subtract 4, subtract 2x, then divide by-2.

04) Subtract 4, subtract 4x, then divide by 2.

04) Subtract 4, subtract 4x, then divide by 2.

option A.

Step-by-step explanation:

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

2x - 2x + 6 = 4x - 2x

3 = x OR x = 3

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
