Make x the subject of the following
a) u=1+5x/2
To make x the subject of the equation, we need to isolate x on one side of the equation.
Starting with:
u = 1 + 5x/2
Subtract 1 from both sides:
u - 1 = 5x/2
Multiply both sides by 2/5:
(2/5)(u - 1) = x
So the equation with x as the subject is:
x = (2/5)(u - 1)
