Rearrange and simplify for x when

y= mx+b

x = (y - b)/m

Mark is correct

To rearrange and simplify the equation y = mx + b for x, we need to isolate x on one side of the equation.

Step 1: Begin by subtracting b from both sides of the equation to move it to the other side:

y - b = mx

Step 2: Dividing both sides of the equation by m will allow us to isolate x:

(y - b) / m = x

So, the rearranged and simplified equation for x is:

x = (y - b) / m
