-\frac{5}{2}x-\frac{5}{3}y-x=4
Combine -2x and -\frac{1}{2}x to get -\frac{5}{2}x.
-\frac{7}{2}x-\frac{5}{3}y=4
Combine -\frac{5}{2}x and -x to get -\frac{7}{2}x.
-\frac{7}{2}x=4+\frac{5}{3}y
Add \frac{5}{3}y to both sides.
-\frac{7}{2}x=\frac{5y}{3}+4
The equation is in standard form.
\frac{-\frac{7}{2}x}{-\frac{7}{2}}=\frac{\frac{5y}{3}+4}{-\frac{7}{2}}
Divide both sides of the equation by -\frac{7}{2}, which is the same as multiplying both sides by the reciprocal of the fraction.
x=\frac{\frac{5y}{3}+4}{-\frac{7}{2}}
Dividing by -\frac{7}{2} undoes the multiplication by -\frac{7}{2}.
x=-\frac{10y}{21}-\frac{8}{7}
Divide 4+\frac{5y}{3} by -\frac{7}{2} by multiplying 4+\frac{5y}{3} by the reciprocal of -\frac{7}{2}.
-\frac{5}{2}x-\frac{5}{3}y-x=4
Combine -2x and -\frac{1}{2}x to get -\frac{5}{2}x.
-\frac{7}{2}x-\frac{5}{3}y=4
Combine -\frac{5}{2}x and -x to get -\frac{7}{2}x.
-\frac{5}{3}y=4+\frac{7}{2}x
Add \frac{7}{2}x to both sides.
-\frac{5}{3}y=\frac{7x}{2}+4
The equation is in standard form.
\frac{-\frac{5}{3}y}{-\frac{5}{3}}=\frac{\frac{7x}{2}+4}{-\frac{5}{3}}
Divide both sides of the equation by -\frac{5}{3}, which is the same as multiplying both sides by the reciprocal of the fraction.
y=\frac{\frac{7x}{2}+4}{-\frac{5}{3}}
Dividing by -\frac{5}{3} undoes the multiplication by -\frac{5}{3}.
y=-\frac{21x}{10}-\frac{12}{5}
Divide 4+\frac{7x}{2} by -\frac{5}{3} by multiplying 4+\frac{7x}{2} by the reciprocal of -\frac{5}{3}.
