Question

(x+4,5)(6x-1)-(3x+1,6)(2x-1)=-3,8x

Answer 1

$(x+4,5)(6x-1)-(3x+1,6)(2x-1)=-3,8x \\ 6 x^{2} -x+27x-4.5-(6 x^{2} -3x+3.2x-1.6)=-3.8x \\ 6 x^{2} -x+27-4.5-(6 x^{2} +0.2x-1.6)=-3.8x \\ 6 x^{2} -x+27-4.5-6 x^{2} -0/2x+1/6=-3.8x \\ 25.8x-2.9=-3.8x \\ 25.8x+3.8x=2.9 \\ 29.6x=2.9 \\ x= \frac{29}{296}$
