3\left(1\times 2+1\right)\left(x-\frac{2}{3}\right)=1.2
Multiply both sides of the equation by 6, the least common multiple of 2,3.
3\left(2+1\right)\left(x-\frac{2}{3}\right)=1.2
Multiply 1 and 2 to get 2.
3\times 3\left(x-\frac{2}{3}\right)=1.2
Add 2 and 1 to get 3.
9\left(x-\frac{2}{3}\right)=1.2
Multiply 3 and 3 to get 9.
9x+9\left(-\frac{2}{3}\right)=1.2
Use the distributive property to multiply 9 by x-\frac{2}{3}.
9x+\frac{9\left(-2\right)}{3}=1.2
Express 9\left(-\frac{2}{3}\right) as a single fraction.
9x+\frac{-18}{3}=1.2
Multiply 9 and -2 to get -18.
9x-6=1.2
Divide -18 by 3 to get -6.
9x=1.2+6
Add 6 to both sides.
9x=7.2
Add 1.2 and 6 to get 7.2.
x=\frac{7.2}{9}
Divide both sides by 9.
x=\frac{72}{90}
Expand \frac{7.2}{9} by multiplying both numerator and the denominator by 10.
x=\frac{4}{5}
Reduce the fraction \frac{72}{90} to lowest terms by extracting and canceling out 18.
