Given the equation:

S = ½( u + v )t

Solve for u.

Solution:

In order to solve for u, we can multiply first both sides by 2, in order to cancel out ½.

S = ½ ( u + v ) t

(2) S = (2) ½ ( u  + v )  t

2s = ( u + v ) t

Divide both sides by t in order to cancel out t on the other side of the equation.

2s/t = ((u + v)t)/t

2s/t = u + v

Transpose v to the other side of the equation in order to determine the value of u. Note that in transposing a number, the sign changes.

u = 2s/t - v

Final answer:

u = 2s/t - v
