Step 1: Write the given equation.
The equation is:
EL=R−x2a
Step 2: Multiply both sides by (R−x) to remove it from the denominator.
(R−x)⋅EL=2a
Step 3: Divide both sides by EL (or multiply by LE) to isolate (R−x).
R−x=2a⋅LE
R−x=L2aE
Step 4: Add x to both sides to make R the subject.
R=L2aE+x
The final answer is:
R=L2aE+x
