\frac{3}{20}\times 70x+\frac{5}{100}\times 17y=400
Reduce the fraction \frac{15}{100} to lowest terms by extracting and canceling out 5.
\frac{21}{2}x+\frac{5}{100}\times 17y=400
Multiply \frac{3}{20} and 70 to get \frac{21}{2}.
\frac{21}{2}x+\frac{1}{20}\times 17y=400
Reduce the fraction \frac{5}{100} to lowest terms by extracting and canceling out 5.
\frac{21}{2}x+\frac{17}{20}y=400
Multiply \frac{1}{20} and 17 to get \frac{17}{20}.
\frac{21}{2}x=400-\frac{17}{20}y
Subtract \frac{17}{20}y from both sides.
\frac{21}{2}x=-\frac{17y}{20}+400
The equation is in standard form.
\frac{\frac{21}{2}x}{\frac{21}{2}}=\frac{-\frac{17y}{20}+400}{\frac{21}{2}}
Divide both sides of the equation by \frac{21}{2}, which is the same as multiplying both sides by the reciprocal of the fraction.
x=\frac{-\frac{17y}{20}+400}{\frac{21}{2}}
Dividing by \frac{21}{2} undoes the multiplication by \frac{21}{2}.
x=-\frac{17y}{210}+\frac{800}{21}
Divide 400-\frac{17y}{20} by \frac{21}{2} by multiplying 400-\frac{17y}{20} by the reciprocal of \frac{21}{2}.
\frac{3}{20}\times 70x+\frac{5}{100}\times 17y=400
Reduce the fraction \frac{15}{100} to lowest terms by extracting and canceling out 5.
\frac{21}{2}x+\frac{5}{100}\times 17y=400
Multiply \frac{3}{20} and 70 to get \frac{21}{2}.
\frac{21}{2}x+\frac{1}{20}\times 17y=400
Reduce the fraction \frac{5}{100} to lowest terms by extracting and canceling out 5.
\frac{21}{2}x+\frac{17}{20}y=400
Multiply \frac{1}{20} and 17 to get \frac{17}{20}.
\frac{17}{20}y=400-\frac{21}{2}x
Subtract \frac{21}{2}x from both sides.
\frac{17}{20}y=-\frac{21x}{2}+400
The equation is in standard form.
\frac{\frac{17}{20}y}{\frac{17}{20}}=\frac{-\frac{21x}{2}+400}{\frac{17}{20}}
Divide both sides of the equation by \frac{17}{20}, which is the same as multiplying both sides by the reciprocal of the fraction.
y=\frac{-\frac{21x}{2}+400}{\frac{17}{20}}
Dividing by \frac{17}{20} undoes the multiplication by \frac{17}{20}.
y=\frac{8000-210x}{17}
Divide 400-\frac{21x}{2} by \frac{17}{20} by multiplying 400-\frac{21x}{2} by the reciprocal of \frac{17}{20}.
