2(3x-2)

To simplify the expression 2(3x-2), you can distribute the 2 to both terms inside the parentheses:

2 * 3x = 6x
2 * -2 = -4

Therefore, the expression simplifies to:

6x - 4

12(x-2)

To simplify the expression 12(x-2), you can distribute the 12 to both terms inside the parentheses:

12 * x = 12x
12 * -2 = -24

Therefore, the expression simplifies to:

12x - 24

6x+5

The expression 6x + 5 cannot be simplified any further as there are no like terms to combine. So the simplified form is 6x + 5.

21x-7

The expression 21x - 7 cannot be simplified any further as there are no like terms to combine. So the simplified form is 21x - 7.

5(x-3)

To simplify the expression 5(x-3), you can distribute the 5 to both terms inside the parentheses:

5 * x = 5x
5 * -3 = -15

Therefore, the expression simplifies to:

5x - 15

3(4x-1)

To simplify the expression 3(4x-1), you can distribute the 3 to both terms inside the parentheses:

3 * 4x = 12x
3 * -1 = -3

Therefore, the expression simplifies to:

12x - 3
