Question

Please solve the equation

Answer 1

Answer:

The answer is $17+\frac{39}{2}t$

Step-by-step explanation:

  $\frac{9}{10}(30+5t)+\frac{5}{6}(18t-12)$

$=\frac{9}{10}\times 5(6+t)+\frac{5}{6}\times 6(3t-2)$,

( take 5 common form first and 6 common from the second expression )

$=\frac{9}{2}(6+t)+5(3t-2)$ , simplify by cancelling terms

$=\frac{9}{2}\times 6+\frac{9}{2}t+5\times 3t-5\times 2\\=27+(4.5t+15t)-10\\=17+19.5t\\=17+\frac{39}{2}t$
