does that really say \(\frac{2}{1}\) on the right?
yes
but i know that it's equal to 2
hmm most human beings call that number \(2\)
Since this is written like a proportion, you can start by cross multiplying.
it's problem for proportions
\[\frac{8x-2}{9}=2\iff 8x-2=9\times 2\]
i.e. \[8x-2=18\] solve in two steps a) add 2 b) divide by 8
\(\dfrac{8x - 2}{9} = \dfrac{2}{1} \) \((8x - 2) \times 1 = 9 \times 2\) \(8x - 2 = 18\) Now follow satellite73 above.
