50-x=4\times \frac{0.8}{\frac{1}{2}}
Multiply both sides of the equation by 4.
50-x=4\times 0.8\times 2
Divide 0.8 by \frac{1}{2} by multiplying 0.8 by the reciprocal of \frac{1}{2}.
50-x=4\times 1.6
Multiply 0.8 and 2 to get 1.6.
50-x=6.4
Multiply 4 and 1.6 to get 6.4.
-x=6.4-50
Subtract 50 from both sides.
-x=-43.6
Subtract 50 from 6.4 to get -43.6.
x=43.6
Multiply both sides by -1.
