To solve for x in the equation y = mx + b, we need to isolate x on one side of the equation.
Start by subtracting b from both sides of the equation:
y - b = mx
Next, divide both sides of the equation by m:
(y - b)/m = x
Therefore, the formula for x is x = (y - b)/m.
Solve for each of the formulas for the indicated variable:
y=mx + b for x

If the perimeter of a rectangle is 60ft and its length is 18ft, find its width. (see formula in number 1)
If the perimeter of a rectangle is 60ft and its length is 18ft, find its width.
So the formula for W in terms of P and L is: W = (P - 2L) / 2
So the formula for W in terms of P and L is: W = (P - 2L) / 2
