9x-3=2\left(3x+2\right)\times \frac{R}{\frac{7}{3}}
Use the distributive property to multiply 3 by 3x-1.
9x-3=\left(6x+4\right)\times \frac{R}{\frac{7}{3}}
Use the distributive property to multiply 2 by 3x+2.
9x-3=6x\times \frac{R}{\frac{7}{3}}+4\times \frac{R}{\frac{7}{3}}
Use the distributive property to multiply 6x+4 by \frac{R}{\frac{7}{3}}.
9x-3-6x\times \frac{R}{\frac{7}{3}}=4\times \frac{R}{\frac{7}{3}}
Subtract 6x\times \frac{R}{\frac{7}{3}} from both sides.
9x-6x\times \frac{R}{\frac{7}{3}}=4\times \frac{R}{\frac{7}{3}}+3
Add 3 to both sides.
\left(9-6\times \frac{R}{\frac{7}{3}}\right)x=4\times \frac{R}{\frac{7}{3}}+3
Combine all terms containing x.
\left(-\frac{18R}{7}+9\right)x=\frac{12R}{7}+3
The equation is in standard form.
\frac{\left(-\frac{18R}{7}+9\right)x}{-\frac{18R}{7}+9}=\frac{\frac{12R}{7}+3}{-\frac{18R}{7}+9}
Divide both sides by 9-\frac{18}{7}R.
x=\frac{\frac{12R}{7}+3}{-\frac{18R}{7}+9}
Dividing by 9-\frac{18}{7}R undoes the multiplication by 9-\frac{18}{7}R.
x=\frac{4R+7}{3\left(7-2R\right)}
Divide \frac{12R}{7}+3 by 9-\frac{18}{7}R.
