Answer 1

1.3 t + 2.7 t = 4
Adding 1.3 t and 2.7 t
4 t = 4
t = 4/4
t = 1

Answer 2

SOLUTION

GIVEN

$\displaystyle \sf{ 1.3t + 2.7t = 4}$

TO DETERMINE

$\displaystyle \sf{ 1.3t + 2.7t = 4}$

$\displaystyle \sf{ \implies ( 1.3+ 2.7)t = 4}$

$\displaystyle \sf{ \implies 4t = 4}$

Dividing both sides by 4 we get

$\displaystyle \sf{ \implies \frac{4t}{4} = \frac{4}{4} }$

$\displaystyle \sf{ \implies t = 1 }$

FINAL ANSWER

Hence the required value of t = 1
