Question 986861
solve 9-4/5 (u-3)>1 
:
9 - {{{4/5}}}(u-3) > 1
Subtract 9 from both sides
{{{-4/5}}}(u-3) > 1 - 9
{{{-4/5}}}(u-3) > -8
Get rid of the neg, mult by -1, this reverses the inequality sign
{{{4/5}}}(u-3) < 8
multiply both sides by 5
4(u - 3) < 40
4u - 12 < 40
Add 12 to both sides
4u < 52
u < 52/4
u < 13
