Question

so resolver a equação de 1º grau. t+5/8 - t-2/2 = 1/3

Answer 1

podemos tirar o mmc

 

 t+5/8 - t-2/2 = 1/3

 

(t+5-4t+8)/8=1/3

 

-3t+13=8/3

-3t=8/3-13

-3t=-31/3

t=31/9

Answer 2

$<var>\frac{t+5}{8} - \frac{t-2}{2} = \frac{1}{3}</var>$

 

$<var>\frac{t+5_{x3}}{8_{x3}} - \frac{t-2_{x4}}{2_{x4}} = \frac{1_{x8}}{3_{x8}}</var>$

 

$<var>\frac{3(t+5)}{24} - \frac{12(t-2)}{24} = \frac{8}{24}</var>$

 

$<var>\frac{3t+15}{24} - \frac{12t-24}{24} = \frac{8}{24} \\\\ anula \ os \ denominadores</var>$

 

$<var>3t+15- 12t-24= 8</var>$

 

$<var>3t- 12t= 8 - 15 + 24</var>$

 

$<var>-9t= 31</var>$

 

$<var>-t = \frac{31}{9} \cdot (-1)</var>$

 

$<var>\boxed{t = -\frac{31}{9}}</var>$
