0.4x=0.4-2x-4
Use the distributive property to multiply -2 by x+2.
0.4x=-3.6-2x
Subtract 4 from 0.4 to get -3.6.
0.4x+2x=-3.6
Add 2x to both sides.
2.4x=-3.6
Combine 0.4x and 2x to get 2.4x.
x=\frac{-3.6}{2.4}
Divide both sides by 2.4.
x=\frac{-36}{24}
Expand \frac{-3.6}{2.4} by multiplying both numerator and the denominator by 10.
x=-\frac{3}{2}
Reduce the fraction \frac{-36}{24} to lowest terms by extracting and canceling out 12.
