Answer

The solution is $\frac{14}{9}$

Work Step by Step

$\frac{9}{5}$=$\frac{12}{3x+2}$ 5*12=9(3x+2) 60=27x+18 60-18=27x 42=27x x=$\frac{42}{27}$ x=$\frac{14}{9}$ Check $\frac{9}{5}$=$\frac{12}{3x+2}$ $\frac{9}{5}$=$\frac{12}{3*\frac{14}{9}+2}$ 12*5=9(3*$\frac{14}{9}$+2) 60=3*14+9*2 60=42+18 60=60
