Solving inequality
(0.4x-1)/0.5-(5-x)/2≤(0.03-0.02x)/0.03

In order to solve the inequality conveniently, first remove the decimal point of the inequality
(0.4x-1)/0.5-(5-x)/2≤(0.03-0.02x)/0.03
[10×(0.4x-1)]/[10×0.5]-(5-x)/2≤[100×(0.03-0.02x)]/[100×0.03]
(4x-10)/5-(5-x)/2≤(3-2x)/3
Go to the denominator and multiply both sides by 30
6(4x-10)-15(5-x)≤10(3-2x)
24x-60-75+15x≤30-20x
59x≤165
x≤165/59
