3{[7(x-2)+4][2(2-5)+6]}

=(3)[7(x-2)+4+(-4x+10)+(-6)]

=(3)(7(x-2))+(3)(4)+(3)(-4x+10)+(3)(-6)

=21x-42+12-12x+30-18

=9x 18

=(3)[7(x-2)+4+(-4x+10)+(-6)]

=(3)(7(x-2))+(3)(4)+(3)(-4x+10)+(3)(-6)

3{[7(x - 2) + 4] - [2(2x - 5) + 6]}

= 3[(7x - 14 + 4) - (4x - 10 + 6)]

= 3[(7x - 10) - (4x - 4)]

= 3(7x - 10 - 4x + 4)

= 3(3x - 6)

= 9x - 18

= 3[(7x - 14 + 4) - (4x - 10 + 6)]

= 3[(7x - 10) - (4x - 4)]

= 3(7x - 10 - 4x + 4)

= 3(3x - 6)

= 9x - 18
