## anonymous 5 years ago (15+x)/=20 find x

1. anonymous

alright, we have :$x + 15 = 20 \rightarrow x = 20-15 \rightarrow x = 5$ if that was the question, ^_^

2. anonymous

oh, there was a typo with the question right?

$\frac{15+x}{5} = 20 \rightarrow 15 + x = (20)(5)$$x = 100 - 15$ $x = 85$ ^_^
