Question

Solve for b: (1/t)=(1/a)+(1/b)

Answer 1

How to get answer by Mimiwhatsup:

Let's solve for b.

1/t = 1/a + 1/b

Step 1: Multiply both sides by t.

1= at+bt/ab

Step 2: Multiply both sides by ab.

ab=at+bt

Step 3: Add -bt to both sides.

ab+−bt=at+bt+−bt

ab−bt=at

Step 4: Factor out variable b.

b(a−t)=at

Step 5: Divide both sides by a-t.

b(a−t)/a−t = at/a−t

b= at/a−t
