18+14.4x-46.8=28.8
Use the distributive property to multiply 3.6 by 4x-13.
-28.8+14.4x=28.8
Subtract 46.8 from 18 to get -28.8.
14.4x=28.8+28.8
Add 28.8 to both sides.
14.4x=57.6
Add 28.8 and 28.8 to get 57.6.
x=\frac{57.6}{14.4}
Divide both sides by 14.4.
x=\frac{576}{144}
Expand \frac{57.6}{14.4} by multiplying both numerator and the denominator by 10.
x=4
Divide 576 by 144 to get 4.
