A
$t = \frac{2}{5}$
B
$t = \frac{- 4}{5}$
C
$t = \frac{- 5}{3}$
D
$t = 0$

Solution:

Given equation is

13 - 5 t + 31 t = - 5 + 11 t - 7

.
On rearranging, we get,
⇒

- 5 t + 31 t - 11 t = - 5 - 7 - 13

⇒

(31 - 11 - 5) t = - 25

⇒

15 t = - 25

⇒

t = \frac{- 25}{15}

⇒

t = \frac{- 5}{3}

Hence, the correct option is 3.

From the following equation calculate the value of variable $t$ .

$13 - 5 t + 31 t = - 5 + 11 t - 7$
