Answer 2

To solve the equation 12 - (3x2 + 5x) + (-7x + 3x2) = 0, we can simplify the equation and then solve for x. Let's go step by step:

12 - (3x2 + 5x) + (-7x + 3x2) = 0

Rearranging the terms:

12 - 3x2 - 5x - 7x + 3x2 = 0

Combining like terms:

(12 - 7x - 5x) + (-3x2 + 3x2) = 0

Simplifying further:

12 - 12x = 0

Now, let's isolate the x term by moving the constant to the other side:

-12x = -12

Dividing both sides of the equation by -12:

x = -12 / -12

x = 1

Therefore, the solution to the equation is x = 1.
