2.25t+5=13.5t+14\ \ \ \ |subtract\ 5\ from\ both\ sides\\\\2.25t=13.5t+9\ \ \ \ |subtract\ 13.5t\ from\ both\ sides\\\\-11.25t=9\ \ \ \ \ |divide\ both\ sides\ by\ (-11.25)\\\\t=-(9)/(11.25)\\\\t=-(900)/(1125)\\\\\boxed{t=-0.8}

We have such question
2.25t+5=13.5t+14 /-2.25t (subtract both sides 2.22t)
2.25t-2.25t+5=13.5t-2.25t+14
5=11.25t+14 /-14 (subtract 14 both sides)
5-14=11.25t+14-14
-9=11.25t /:11.25 (divide both sides by 11.25)

-9:11.25
-0.8=x - its the answer
