Hi ,
It is given that ,
0.5( 4 - 2a ) = a - 1.8
multiply on both sides with 10,
we get
10 × ( 0.5 )[ 4 - 2a ] = 10( a- 1.8 )
=> 5( 4 - 2a ) = 10a - 18
=> 20 - 10a = 10a - 10
=> -10a - 10a = -10 - 20
=> -20a = -30
=> a = ( -30 )/( -20 )
Therefore ,
a = 3/2
a = 1.5
I hope this helps you.

Guruji..Small correction.. it should be 20 - 10a = 10a - 18.
