-0.58=\frac{\left(x-30\right)\sqrt{25}}{12}
Divide x-30 by \frac{12}{\sqrt{25}} by multiplying x-30 by the reciprocal of \frac{12}{\sqrt{25}}.
-0.58=\frac{\left(x-30\right)\times 5}{12}
Calculate the square root of 25 and get 5.
-0.58=\frac{5x-150}{12}
Use the distributive property to multiply x-30 by 5.
-0.58=\frac{5}{12}x-\frac{25}{2}
Divide each term of 5x-150 by 12 to get \frac{5}{12}x-\frac{25}{2}.
\frac{5}{12}x-\frac{25}{2}=-0.58
Swap sides so that all variable terms are on the left hand side.
\frac{5}{12}x=-0.58+\frac{25}{2}
Add \frac{25}{2} to both sides.
\frac{5}{12}x=-\frac{29}{50}+\frac{25}{2}
Convert decimal number -0.58 to fraction -\frac{58}{100}. Reduce the fraction -\frac{58}{100} to lowest terms by extracting and canceling out 2.
\frac{5}{12}x=-\frac{29}{50}+\frac{625}{50}
Least common multiple of 50 and 2 is 50. Convert -\frac{29}{50} and \frac{25}{2} to fractions with denominator 50.
\frac{5}{12}x=\frac{-29+625}{50}
Since -\frac{29}{50} and \frac{625}{50} have the same denominator, add them by adding their numerators.
\frac{5}{12}x=\frac{596}{50}
Add -29 and 625 to get 596.
\frac{5}{12}x=\frac{298}{25}
Reduce the fraction \frac{596}{50} to lowest terms by extracting and canceling out 2.
x=\frac{298}{25}\times \frac{12}{5}
Multiply both sides by \frac{12}{5}, the reciprocal of \frac{5}{12}.
x=\frac{298\times 12}{25\times 5}
Multiply \frac{298}{25} times \frac{12}{5} by multiplying numerator times numerator and denominator times denominator.
x=\frac{3576}{125}
Do the multiplications in the fraction \frac{298\times 12}{25\times 5}.
