y = mx + b.  Solve for x:

Subtr. b from both sides.  Then, y - b = mx

Next, divide both sides by m, to isolate x:
       
       mx      y-b
x = ----- = -------           (answer)
        m         m

Important:

"x = _____ - _____ / _____ "

is a bit ambiguous.  Please enclose the numerator inside parentheses, like this:

x = ( _____ - _____ ) / _____      Then it becomes clear that we must perform
 
the subtraction first, before the division.

The resulting equation obtained by solving for x in the equation y = mx + b is :

  • x = (y - b) /m

Given the expression : y = mx + b

To solve for x ; follow the following steps :

STEP 1 :

Subtract b from both sides to isolate mx :

  • y - b = mx + b - b
  • y - b = mx

STEP 2 :

Divide both sides by x in other to isolate x

  • (y - b) / m = mx / m
  • (y - b) /m = x

Therefore, making x the subject gives the final equation as : x = (y - b) /m
