1.6x-3.8+4.2=10
Multiply 0.8 and 2 to get 1.6.
1.6x+0.4=10
Add -3.8 and 4.2 to get 0.4.
1.6x=10-0.4
Subtract 0.4 from both sides.
1.6x=9.6
Subtract 0.4 from 10 to get 9.6.
x=\frac{9.6}{1.6}
Divide both sides by 1.6.
x=\frac{96}{16}
Expand \frac{9.6}{1.6} by multiplying both numerator and the denominator by 10.
x=6
Divide 96 by 16 to get 6.
