2+1.4x-2.8=10.4
Use the distributive property to multiply x-2 by 1.4.
-0.8+1.4x=10.4
Subtract 2.8 from 2 to get -0.8.
1.4x=10.4+0.8
Add 0.8 to both sides.
1.4x=11.2
Add 10.4 and 0.8 to get 11.2.
x=\frac{11.2}{1.4}
Divide both sides by 1.4.
x=\frac{112}{14}
Expand \frac{11.2}{1.4} by multiplying both numerator and the denominator by 10.
x=8
Divide 112 by 14 to get 8.
