-7.6-x=2\left(0.4x-1.8\right)
Add -9.6 and 2 to get -7.6.
-7.6-x=0.8x-3.6
Use the distributive property to multiply 2 by 0.4x-1.8.
-7.6-x-0.8x=-3.6
Subtract 0.8x from both sides.
-7.6-1.8x=-3.6
Combine -x and -0.8x to get -1.8x.
-1.8x=-3.6+7.6
Add 7.6 to both sides.
-1.8x=4
Add -3.6 and 7.6 to get 4.
x=\frac{4}{-1.8}
Divide both sides by -1.8.
x=\frac{40}{-18}
Expand \frac{4}{-1.8} by multiplying both numerator and the denominator by 10.
x=-\frac{20}{9}
Reduce the fraction \frac{40}{-18} to lowest terms by extracting and canceling out 2.
