2.5+x=x\times \frac{5.8}{5.3}
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
2.5+x=x\times \frac{58}{53}
Expand \frac{5.8}{5.3} by multiplying both numerator and the denominator by 10.
2.5+x-x\times \frac{58}{53}=0
Subtract x\times \frac{58}{53} from both sides.
2.5-\frac{5}{53}x=0
Combine x and -x\times \frac{58}{53} to get -\frac{5}{53}x.
-\frac{5}{53}x=-2.5
Subtract 2.5 from both sides. Anything subtracted from zero gives its negation.
x=-2.5\left(-\frac{53}{5}\right)
Multiply both sides by -\frac{53}{5}, the reciprocal of -\frac{5}{53}.
x=-\frac{5}{2}\left(-\frac{53}{5}\right)
Convert decimal number -2.5 to fraction -\frac{25}{10}. Reduce the fraction -\frac{25}{10} to lowest terms by extracting and canceling out 5.
x=\frac{-5\left(-53\right)}{2\times 5}
Multiply -\frac{5}{2} times -\frac{53}{5} by multiplying numerator times numerator and denominator times denominator.
x=\frac{265}{10}
Do the multiplications in the fraction \frac{-5\left(-53\right)}{2\times 5}.
x=\frac{53}{2}
Reduce the fraction \frac{265}{10} to lowest terms by extracting and canceling out 5.
