Answer:

Step-by-step explanation:

Cross multiplication can be used but not in the beginning. First x should be isolated.

$3 +\frac{5}{x}=\frac{7}{x}\\\\$

Now subtract $\frac{5}{x}$ from both sides

$3 = \frac{7}{x}-\frac{5}{x}\\\\3=\frac{7-5}{x}\\\\3=\frac{2}{x}$

In this stage, cross multiplication can be used.

$\frac{3}{1}=\frac{2}{x}\\\\3*x=2*1\\\\x = \frac{2}{3}$
