\frac{20x-42}{19}=x
Use the distributive property to multiply x-2.1 by 20.
\frac{20}{19}x-\frac{42}{19}=x
Divide each term of 20x-42 by 19 to get \frac{20}{19}x-\frac{42}{19}.
\frac{20}{19}x-\frac{42}{19}-x=0
Subtract x from both sides.
\frac{1}{19}x-\frac{42}{19}=0
Combine \frac{20}{19}x and -x to get \frac{1}{19}x.
\frac{1}{19}x=\frac{42}{19}
Add \frac{42}{19} to both sides. Anything plus zero gives itself.
x=\frac{42}{19}\times 19
Multiply both sides by 19, the reciprocal of \frac{1}{19}.
x=42
Cancel out 19 and 19.
