Question

Solve s= P/2 (c+K) for K

Answer 1

\[ s= \frac{p}{2} (c+k)\]
multiply both sides by 2 and divide both sides by p
\[\frac{2}{p} s= c+k\]
subtract both sides by k
\[\frac{2}{p} s-c= k\]
so k is \(\frac{2}{p} s-c\)

Thank-you :D

Answer 3

Solve x-6y=19 for y?

Answer 4

Solve x-6y=19 for y

x-6y = 19
-6y = 19 - x
-1/6(-6y) = (-1/6)(19 - x)
y = -19/6 + x/6
y = (1/6) x - 19/6
