d = rt solve for r

Answer 1

To solve for r, we can divide both sides of the equation by t:

d / t = r

Therefore, r = d / t.

Answer 2

P = a + b + c
solve for a

Answer 3

To solve for a, we can isolate it on one side of the equation.

P = a + b + c

By subtracting b and c from both sides, we have:

P - b - c = a

So, a = P - b - c.
