1.

 ax-b=c, for x         add b to both sides

ax = b + c               divide both sides by 

x = [ b + c ] / a

 

2.

15x+1=y, for x          subtract 1 from both sides

15x = y - 1                divide both sides by 15

x = [ y - 1 ] / 15

 

 

3.

(x+f)+2=j, for x       subtract 2 from both sides

x + f  = j - 2             subtract f  from both sides

 x = j - 2 - f
