Answer 2

Solving the Equation 2x(x-3)-(x-4)(2x+7)=43

To solve the equation 2x(x-3)-(x-4)(2x+7)=43, we can follow these steps:

1. Expand and Simplify the Equation: - Expand the terms and simplify the equation to make it easier to solve.

2. Combine Like Terms: - Combine like terms to further simplify the equation.

3. Isolate the Variable: - Isolate the variable to solve for its value.

Let's proceed with solving the equation step by step.

Step 1: Expand and Simplify the Equation

Expanding the equation 2x(x-3)-(x-4)(2x+7)=43 gives us: 2x^2 - 6x - (2x^2 + 7x - 8x - 28) = 43

Step 2: Combine Like Terms

Combining like terms, we get: 2x^2 - 6x - 2x^2 - 7x + 8x + 28 = 43 -5x + 28 = 43

Step 3: Isolate the Variable

Isolating the variable, we have: -5x = 43 - 28 -5x = 15

Finally, solving for x: x = -15/5 x = -3

So, the solution to the equation 2x(x-3)-(x-4)(2x+7)=43 is x = -3.
