Solve a Linear Equation Program | Dataford Interview Questions

Write a program that solves the linear equation 2x-7 = 3x+5.

Implement solve_linear_equation(left_coefficient, left_constant, right_coefficient, right_constant), which solves equations of the form a*x + b = c*x + d. Return the numeric value of x. For the stated equation, the result is -12.

Constraints

The inputs are integers or floating-point numbers.
left_coefficient - right_coefficient is not zero.
The equation has exactly one solution.

Function Signature
