To solve for x means we make x the subject of the formula. The value of x is:
[tex]x = \frac{d - f}{f}[/tex]
Given that:
[tex]d = f + fx[/tex]
To solve for x, we make use of the following steps
[tex]d = f + fx[/tex]
Subtract f from both sides
[tex]d - f =fx[/tex]
Isolate x: Divide both sides by f
[tex]\frac{d - f}{f} = x[/tex]
So, we have:
[tex]x = \frac{d - f}{f}[/tex]
