46+10.3x-15.5x\leq 20
Subtract 15.5x from both sides.
46-5.2x\leq 20
Combine 10.3x and -15.5x to get -5.2x.
-5.2x\leq 20-46
Subtract 46 from both sides.
-5.2x\leq -26
Subtract 46 from 20 to get -26.
x\geq \frac{-26}{-5.2}
Divide both sides by -5.2. Since -5.2 is negative, the inequality direction is changed.
x\geq \frac{-260}{-52}
Expand \frac{-26}{-5.2} by multiplying both numerator and the denominator by 10.
x\geq 5
Divide -260 by -52 to get 5.
