Question

5×x-1 supra 10 = 2×x-3 supra 6 +1supra3​

Answer 1

Răspuns:

$\bf \dfrac{5x-1}{10}=\dfrac{2x-3}{6}+\dfrac{^{2)} 1~}{3}$

$\bf \dfrac{5x-1}{10}=\dfrac{2x-3+2}{6}\implies \dfrac{5x-1}{10}=\dfrac{2x-1}{6}\implies$

$\bf 6\cdot(5x-1)=10\cdot(2x-1)\implies 30x-6=20x-10\implies$

$\bf 30x-20x=-10+6\implies 10x =-4\implies$

$\red{\boxed{\bf x =-\frac{2}{5} }}$
