Add 4 to the second equation to get
.. 3b = 6
Substitute this into the first equation to get
.. 2a +6 = 12
.. 2a = 6 . . . . . . . subtract 6
.. a = 3 . . . . . . . . divide by 2
The value of a is 3.
h =
multiply both sides by 2 to eliminate the fraction
2A = ( b + c)h
isolate h by dividing both sides by (b + c)
h =
