## Functions Modeling Change: A Preparation for Calculus, 5th Edition

$x=\frac{7}{16}$
As long as $x=0$ is not a solution to the equation (which it isn't, since division by zero isn't possible), both sides of the equation can be multiplied by $2x$. This leaves $$4+3=16x$$ $$7=16x$$ Dividing by $16$ yields $$x=\frac{7}{16}$$
