Step-by-step explanation:
To solve the equation
graphically, we need to consider left and right parts of this equation separately.
Left side gives us the function
The graph of this function is shown with green curve in attached diagram.
Right side gives us the function
The graph of this function is shown with blue curve in attached diagram.
The x-coordinates of the points of their intersections are the solutions to the equation 
From the graph you can see that the solutions are

The return on equity for the firm is 18.75%.
<h3>Return on equity</h3>
Return on equity=Return on assets +[ (Debt/Equity ratio)×(Return on assets-Return on debt)]
Let plug in the formula
Return on equity=.15+ [(.75)× (.15-.10)]
Return on assets=.15+ (.75×0.05)
Return on assets=.15+0.0375
Return on equity=0.1875×100
Return on equity=18.75%
Therefore the return on equity ratio is 18.75%.
