Solve the equation.

Question

R= as/a + s for s.

The solution is s = ?

Answer 1

R = as/a + s    

To solve for s, you must get s by itself on either side of the = sign.  To do this, you can subtract as/a from both sides.

R - as/a = as/a - as/a + s

simplify:

R - as/a  = s

Flip equation so it looks more natural for solving for s:

s = R - as/a
