First get like things on the same side:
-5/6b - 1/2b= -2/3 - 3/4
Then find equivalent fractions to make the equation easier to solve.
-5/6b - 3/6b= -8/12 - 9/12
Then just add things together and solve.
-8/6b= -17/12
-8b= 6(-17/12)
-8b= -17/2
b= (-17/2)/-8
b= 17/16
You can then plug the answer back into the original question to make sure it is the correct answer.
If ABC type question, then sometimes. If its extended, then only when the lines coincide with each other or if one of the lines aren't linear.
16cm
Dividing 81.9 cm^2 by 4.9cm will give you about a 16 cm height.
:) Good Luck
