Solve the equation to find the value of x 3x (12x + 1) and (16x - 7) using the Triangle Sum Sum Therom

The equation you have provided is not an equation but an expression. To solve an equation, there needs to be an equal sign. If you meant to solve the equation:

3x(12x + 1) = (16x - 7)

Here's how you can solve it:

First, distribute 3x to the terms inside the parentheses:

36x^2 + 3x = 16x - 7

Rearrange the equation to have all the terms on one side:

36x^2 + 3x - 16x + 7 = 0

Combine like terms:

36x^2 - 13x + 7 = 0

Now, you can solve this quadratic equation using factoring, completing the square, or using the quadratic formula. However, the Triangle Sum Sum Theorem has nothing to do with solving this equation.
