Answer:


Step-by-step explanation:
← Equation 1

By simplifying the above equation we get,
(Simplifying the brackets)
(By subtracting
from
) ← Equation 2
Multiply Equation 1 by 5 and Equation 2 by 3 and add them together.
Equation 1 multiplied by 5 will give,

Equation 2 multiplied by 3 will give,

Add those together,
(After simplifying
values)
Therefor 
By substituting
to Equation 1 we get,


Therefor we can say,


D. You can tell by the opened and closed line dots.
