2x-9.3-0.8x=5.1
Subtract 0.8x from both sides.
1.2x-9.3=5.1
Combine 2x and -0.8x to get 1.2x.
1.2x=5.1+9.3
Add 9.3 to both sides.
1.2x=14.4
Add 5.1 and 9.3 to get 14.4.
x=\frac{14.4}{1.2}
Divide both sides by 1.2.
x=\frac{144}{12}
Expand \frac{14.4}{1.2} by multiplying both numerator and the denominator by 10.
x=12
Divide 144 by 12 to get 12.
