Question 74615
{{{5(3t-(t-4)) - 11 <= - 12(t-6)-(-t)}}}
{{{5(3t - t + 4) - 11 <= -12t + 72 + t}}}
{{{15t -5t + 20 -11 <= -11t + 72}}}
{{{10t + 9 <= -11t + 72}}}
{{{21t <= 63}}}
{{{t <= 3}}}
check
If t = 3, are both sides equal?
{{{5(3*3-(3 - 4)) - 11 <= -12(3 - 6) -(-3)}}}
{{{5(9 + 1) - 11 <= -12(-3) - (-3)}}}
{{{50 - 11 <= 36 + 3}}}
{{{39 = 39}}}
OK
