Make x the subject of the following

Question

a) u=1+5x/2

Answer 1

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)
