20.5=x\left(-2.1\right)
Subtract 4.1 from 2 to get -2.1.
x\left(-2.1\right)=20.5
Swap sides so that all variable terms are on the left hand side.
x=\frac{20.5}{-2.1}
Divide both sides by -2.1.
x=\frac{205}{-21}
Expand \frac{20.5}{-2.1} by multiplying both numerator and the denominator by 10.
x=-\frac{205}{21}
Fraction \frac{205}{-21} can be rewritten as -\frac{205}{21} by extracting the negative sign.
