Which of the following shows the true solution to the logarithmic equation solved below?
Log2(x)+log2(x+7)=3
Log2[x(x+7)]=3
X(x+7)=2^3
X^2+7x-8=0
(X+8)(x-1)=0
X=-8,1

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

he is going to fill two shelves and the third shelf will only have five video games

i think the answer is b x = 1, y = 35/2
