1) To solve the equation 6x - 5 = 3x + 7, we first need to get all the x terms on one side of the equation.
Subtracting 3x from both sides, we get:
6x - 3x - 5 = 3x - 3x + 7
3x - 5 = 7
Next, add 5 to both sides:
3x - 5 + 5 = 7 + 5
3x = 12
Finally, divide by 3 to solve for x:
3x/3 = 12/3
x = 4

Therefore, the solution to the equation 6x - 5 = 3x + 7 is x = 4.

2) To solve the equation (3x - 9)(2x - 4) = 0, we need to set each factor equal to zero and solve for x separately.

Setting 3x - 9 = 0:
3x = 9
x = 3

Setting 2x - 4 = 0:
2x = 4
x = 2

So the solutions to the equation (3x - 9)(2x - 4) = 0 are x = 3 and x = 2.
