140xx_{40}\times 5=100
Multiply 7 and 20 to get 140.
700xx_{40}=100
Multiply 140 and 5 to get 700.
700x_{40}x=100
The equation is in standard form.
\frac{700x_{40}x}{700x_{40}}=\frac{100}{700x_{40}}
Divide both sides by 700x_{40}.
x=\frac{100}{700x_{40}}
Dividing by 700x_{40} undoes the multiplication by 700x_{40}.
x=\frac{1}{7x_{40}}
Divide 100 by 700x_{40}.
140xx_{40}\times 5=100
Multiply 7 and 20 to get 140.
700xx_{40}=100
Multiply 140 and 5 to get 700.
\frac{700xx_{40}}{700x}=\frac{100}{700x}
Divide both sides by 700x.
x_{40}=\frac{100}{700x}
Dividing by 700x undoes the multiplication by 700x.
x_{40}=\frac{1}{7x}
Divide 100 by 700x.
