Refine:
\(\frac{2x-4}{10}\)
factor out common term 2 :
\(\frac{2(x-2)}{10}\)
Cancel the common factor 2 :
\(\frac{x-2}{5}\)
Refine:
\(\frac{2x}{20}\)
\(\frac{x-2}{5} = \frac{x}{10}\)
find least common multiplier of 5 and 10
Multiply by LCM = 10
\(\frac{x-2}{5} *10 = \frac{x}{10} *10\)
\(2(x-2)=x\)
\(2x - 4 = x\)
Add 4 to both sides:
\(2x-4+4 = x+4\)
\(2x = x + 4\)
\(2x - x = 4\)
\(x = 4\)
hope this helps!
