Question

typing speed is calculated using the formula s= (w-10e)/5 solve the formula for e in terms s and w

Answer 1

So you have s=(w-10e)/5         

To get rid of the 5, multiply the equation by 5, then to the other side.

So now it is 5s=w-10e

Now subtract w. So its now 5s-w=-10e

Now divide the -10. So now it is e=(5s-w)/-10

And it will not simplify because the s and w have different coefficients.
