X+ 6y = 2 4x - 3y = 10 pick the first step to solving this system of equations using the addition method. add the equation first to get: 5x + 3y = 12 and then solve for x. add -6y to both sides of the equation to isolate the x variable in the top equation. multiply the top equation by 4 thus eliminating the x variable when the equations are added together. multiply the bottom equation by 2 thus eliminating the y variable when the equations are added together.

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
