3{[7(x - 2) + 4] - [2(2x - 5) + 6]}
:
Begin with inside brackets, multiply and clear those
3{[7x - 14 + 4] - [4x - 10 + 6]}
Which is
3{[7x - 10] - [4x - 4]}
removing the next inside bracket, involves changing the signs of (4x - 10) because of the negative
3{7x - 10 - 4x + 4]}
:
3(3x - 6) = 9x - 18 your answer!!

3{[7(x-2)+4]-[2(2x-5)-0]}
3{[7x-14+4]-[4x-10]-0}
21x-42+12-12x+30-0
21x-42-12x+42
9x
I cannot find the -18 because the numbers cancil
Good luck
