1.) 3a - (b-2a)
= 3a - b + 2a
= 3a + 2a - b [LIKE TERMS]
= 5a - b
2.) x-[2y-{3x-(2y-3z)}]
= x - 2y-{3x-(2y-3z)}
= x - 2y - 3x - 2y +3z
= x - 3x - 2y - 2y +3z
= - 2x - 4y +3z
= 3a - b + 2a
= 3a + 2a - b [LIKE TERMS]
= 5a - b
2.) x-[2y-{3x-(2y-3z)}]
= x - 2y-{3x-(2y-3z)}
= x - 2y - 3x - 2y +3z
= x - 3x - 2y - 2y +3z
