6x(x+2) - 0.5(12x^2 - 7x) - 31 = 0Expanding the equation:6x^2 + 12x - 6x^2 + 3.5x - 31 = 0Combining like terms:15.5x - 31 = 015.5x = 31x = 31 / 15.5x = 2
Therefore, the solution to the equation is x = 2.
6x(x+2) - 0.5(12x^2 - 7x) - 31 = 0
Expanding the equation:
6x^2 + 12x - 6x^2 + 3.5x - 31 = 0
Combining like terms:
15.5x - 31 = 0
15.5x = 31
x = 31 / 15.5
x = 2
Therefore, the solution to the equation is x = 2.
