1) Subtract -7x from 5x

= 5x – ( -7x)

=5x + 7x

= 12x

_______________________________________________________________________

2)x

=(4x

= 4x

=4x

= 3x

_______________________________________________________________________

3)What should be subtracted from a

a

Let 'X' denote the required expression,

(a

Hence , X = (a

= a

= a

= a

_________________________________________________________________

4)Subtract a

= [(3a

= (3a

= (3a

= 3a

=

= 2a
