Question 674908
{{{5a + 3 <= 6a}}}
...
group the variables on one side
{{{5a + cross(3) - cross(3) - highlight(6a) <= cross(6a) - cross(6a) - highlight(3)}}}
{{{5a - 6a <= -3}}}
...
combine like terms
{{{-a <= -3}}}
...
divide both sides by -1 and note the sign change for dividing by a negative
{{{cross(-1)a/cross(-1) >= -3/highlight(-1)}}}
...
{{{highlight_green(a>=3)}}}
