\frac{x+3}{4}=\frac{y+4}{6+4}
Add 1 and 3 to get 4.
\frac{x+3}{4}=\frac{y+4}{10}
Add 6 and 4 to get 10.
\frac{1}{4}x+\frac{3}{4}=\frac{y+4}{10}
Divide each term of x+3 by 4 to get \frac{1}{4}x+\frac{3}{4}.
\frac{1}{4}x+\frac{3}{4}=\frac{1}{10}y+\frac{2}{5}
Divide each term of y+4 by 10 to get \frac{1}{10}y+\frac{2}{5}.
\frac{1}{4}x=\frac{1}{10}y+\frac{2}{5}-\frac{3}{4}
Subtract \frac{3}{4} from both sides.
\frac{1}{4}x=\frac{1}{10}y-\frac{7}{20}
Subtract \frac{3}{4} from \frac{2}{5} to get -\frac{7}{20}.
\frac{1}{4}x=\frac{y}{10}-\frac{7}{20}
The equation is in standard form.
\frac{\frac{1}{4}x}{\frac{1}{4}}=\frac{\frac{y}{10}-\frac{7}{20}}{\frac{1}{4}}
Multiply both sides by 4.
x=\frac{\frac{y}{10}-\frac{7}{20}}{\frac{1}{4}}
Dividing by \frac{1}{4} undoes the multiplication by \frac{1}{4}.
x=\frac{2y-7}{5}
Divide \frac{y}{10}-\frac{7}{20} by \frac{1}{4} by multiplying \frac{y}{10}-\frac{7}{20} by the reciprocal of \frac{1}{4}.
\frac{x+3}{4}=\frac{y+4}{6+4}
Add 1 and 3 to get 4.
\frac{x+3}{4}=\frac{y+4}{10}
Add 6 and 4 to get 10.
\frac{1}{4}x+\frac{3}{4}=\frac{y+4}{10}
Divide each term of x+3 by 4 to get \frac{1}{4}x+\frac{3}{4}.
\frac{1}{4}x+\frac{3}{4}=\frac{1}{10}y+\frac{2}{5}
Divide each term of y+4 by 10 to get \frac{1}{10}y+\frac{2}{5}.
\frac{1}{10}y+\frac{2}{5}=\frac{1}{4}x+\frac{3}{4}
Swap sides so that all variable terms are on the left hand side.
\frac{1}{10}y=\frac{1}{4}x+\frac{3}{4}-\frac{2}{5}
Subtract \frac{2}{5} from both sides.
\frac{1}{10}y=\frac{1}{4}x+\frac{7}{20}
Subtract \frac{2}{5} from \frac{3}{4} to get \frac{7}{20}.
\frac{1}{10}y=\frac{x}{4}+\frac{7}{20}
The equation is in standard form.
\frac{\frac{1}{10}y}{\frac{1}{10}}=\frac{\frac{x}{4}+\frac{7}{20}}{\frac{1}{10}}
Multiply both sides by 10.
y=\frac{\frac{x}{4}+\frac{7}{20}}{\frac{1}{10}}
Dividing by \frac{1}{10} undoes the multiplication by \frac{1}{10}.
y=\frac{5x+7}{2}
Divide \frac{x}{4}+\frac{7}{20} by \frac{1}{10} by multiplying \frac{x}{4}+\frac{7}{20} by the reciprocal of \frac{1}{10}.
