Impara online a risolvere i problemi di passo dopo passo. log((2*x+5)/5)=log(2*x+-2)+log(1/4). Applicare la formula: \log_{a}\left(x\right)+\log_{a}\left(y\right)=\log_{a}\left(xy\right), dove a=10, x=2x-2 e y=\frac{1}{4}. Applicare la formula: \log_{a}\left(x\right)=\log_{a}\left(y\right)\to x=y, dove a=10, x=\frac{2x+5}{5} e y=\frac{1}{4}\left(2x-2\right). Applicare la formula: x\left(a+b\right)=xa+xb, dove a=2x, b=-2, x=\frac{1}{4} e a+b=2x-2. Applicare la formula: a\frac{b}{c}=\frac{ba}{c}, dove a=x, b=1 e c=2.
