12-10\times 2x\geq 5x
Multiply both sides of the equation by 30, the least common multiple of 5,3,6. Since 30 is positive, the inequality direction remains the same.
12-20x\geq 5x
Multiply -10 and 2 to get -20.
12-20x-5x\geq 0
Subtract 5x from both sides.
12-25x\geq 0
Combine -20x and -5x to get -25x.
-25x\geq -12
Subtract 12 from both sides. Anything subtracted from zero gives its negation.
x\leq \frac{-12}{-25}
Divide both sides by -25. Since -25 is negative, the inequality direction is changed.
x\leq \frac{12}{25}
Fraction \frac{-12}{-25} can be simplified to \frac{12}{25} by removing the negative sign from both the numerator and the denominator.
