123x-4.5\times \frac{1}{1000000}=4.5\times 10^{-7}
Calculate 10 to the power of -6 and get \frac{1}{1000000}.
123x-\frac{9}{2000000}=4.5\times 10^{-7}
Multiply 4.5 and \frac{1}{1000000} to get \frac{9}{2000000}.
123x-\frac{9}{2000000}=4.5\times \frac{1}{10000000}
Calculate 10 to the power of -7 and get \frac{1}{10000000}.
123x-\frac{9}{2000000}=\frac{9}{20000000}
Multiply 4.5 and \frac{1}{10000000} to get \frac{9}{20000000}.
123x=\frac{9}{20000000}+\frac{9}{2000000}
Add \frac{9}{2000000} to both sides.
123x=\frac{99}{20000000}
Add \frac{9}{20000000} and \frac{9}{2000000} to get \frac{99}{20000000}.
x=\frac{\frac{99}{20000000}}{123}
Divide both sides by 123.
x=\frac{99}{20000000\times 123}
Express \frac{\frac{99}{20000000}}{123} as a single fraction.
x=\frac{99}{2460000000}
Multiply 20000000 and 123 to get 2460000000.
x=\frac{33}{820000000}
