Carter Dunn · Answer 1

For this equation, you must bring the pro numeral you want to leave to the left and move everything to the right.

V=4-2U (as when you move from one side to the other the sign changes)

2U=4-V (change of sign)

U = (4-V) / 2 (dividing both sides by 2 to get U by itself)

V=4-2u and U=2 - (1/2) v
