 Solve for  b . y   =   mx + b Subtract  mx  from both sides of the equation. y - mx   =   b Solve for  b . A   =   h(b + c) Divide both sides of the equation by  h  . A / h   =   b + c Subtract  c  from both sides of the equation. A / h  -  c   =   b Solve for r2 . A   =   4r2 Divide both sides of the equation by  4 . A / 4   =   r2 Solve for  x . 7x - y  =  14 First add  y  to both sides. See if you can figure the rest out. Solve for  i . R  =  (E / i) Multiply both sides of the equation by  i . i * R  =  E Divide both sides of the equation by  R. i  =  E / R Solve for  L . Using this as the equation  A = $$\frac{r}2$$L , A  =  $$\frac{r}2$$L multiply both sides by  $$\frac2r$$ . $$\frac2r$$ * A  = $$\frac{2}{r}$$ * $$\frac{r}{2}$$ * L $$\frac{2A}{r}$$  =  L If you meant for the equation to be  A = $$\frac{r}{2L}$$ , then it is different!
