Answer 1

Ответ:

Объяснение:

(3x-2)(4x+1)-6x(2x+3)=67

12x²+3x-8x-2-12x²-18x=67

-23x-2=67

-23x=69

x=-3

Answer 2

Let's solve the given equation step by step:

First, let's expand the expressions on both sides of the equation:

(3x - 2)(4x + 1) - 6x(2x + 3) = 67

Expanding the left side:

12x^2 + 3x - 8x - 2 - 12x^2 - 18x = 67

Simplifying the equation:

-5x - 2 - 18x = 67

Combining like terms:

-23x - 2 = 67

Next, let's isolate the variable x. We can do this by moving the constant term to the right side of the equation:

-23x = 67 + 2

-23x = 69

Finally, we can solve for x by dividing both sides of the equation by -23:

x = 69 / -23

Simplifying the expression:

x = -3

Therefore, the solution to the equation (3x - 2)(4x + 1) - 6x(2x + 3) = 67 is x = -3.
