8x\geq -4.2+5.8
Add 5.8 to both sides.
8x\geq 1.6
Add -4.2 and 5.8 to get 1.6.
x\geq \frac{1.6}{8}
Divide both sides by 8. Since 8 is positive, the inequality direction remains the same.
x\geq \frac{16}{80}
Expand \frac{1.6}{8} by multiplying both numerator and the denominator by 10.
x\geq \frac{1}{5}
Reduce the fraction \frac{16}{80} to lowest terms by extracting and canceling out 16.
