\frac{3}{2}x-\left(1-\frac{1}{2}\right)y-5+\frac{1}{2}=0
Subtract \frac{1}{2} from 2 to get \frac{3}{2}.
\frac{3}{2}x-\frac{1}{2}y-5+\frac{1}{2}=0
Subtract \frac{1}{2} from 1 to get \frac{1}{2}.
\frac{3}{2}x-\frac{1}{2}y-\frac{9}{2}=0
Add -5 and \frac{1}{2} to get -\frac{9}{2}.
\frac{3}{2}x-\frac{9}{2}=\frac{1}{2}y
Add \frac{1}{2}y to both sides. Anything plus zero gives itself.
\frac{3}{2}x=\frac{1}{2}y+\frac{9}{2}
Add \frac{9}{2} to both sides.
\frac{3}{2}x=\frac{y+9}{2}
The equation is in standard form.
\frac{\frac{3}{2}x}{\frac{3}{2}}=\frac{y+9}{\frac{3}{2}\times 2}
Divide both sides of the equation by \frac{3}{2}, which is the same as multiplying both sides by the reciprocal of the fraction.
x=\frac{y+9}{\frac{3}{2}\times 2}
Dividing by \frac{3}{2} undoes the multiplication by \frac{3}{2}.
x=\frac{y}{3}+3
Divide \frac{9+y}{2} by \frac{3}{2} by multiplying \frac{9+y}{2} by the reciprocal of \frac{3}{2}.
\frac{3}{2}x-\left(1-\frac{1}{2}\right)y-5+\frac{1}{2}=0
Subtract \frac{1}{2} from 2 to get \frac{3}{2}.
\frac{3}{2}x-\frac{1}{2}y-5+\frac{1}{2}=0
Subtract \frac{1}{2} from 1 to get \frac{1}{2}.
\frac{3}{2}x-\frac{1}{2}y-\frac{9}{2}=0
Add -5 and \frac{1}{2} to get -\frac{9}{2}.
-\frac{1}{2}y-\frac{9}{2}=-\frac{3}{2}x
Subtract \frac{3}{2}x from both sides. Anything subtracted from zero gives its negation.
-\frac{1}{2}y=-\frac{3}{2}x+\frac{9}{2}
Add \frac{9}{2} to both sides.
-\frac{1}{2}y=\frac{9-3x}{2}
The equation is in standard form.
\frac{-\frac{1}{2}y}{-\frac{1}{2}}=\frac{9-3x}{-\frac{1}{2}\times 2}
Multiply both sides by -2.
y=\frac{9-3x}{-\frac{1}{2}\times 2}
Dividing by -\frac{1}{2} undoes the multiplication by -\frac{1}{2}.
y=3x-9
Divide \frac{-3x+9}{2} by -\frac{1}{2} by multiplying \frac{-3x+9}{2} by the reciprocal of -\frac{1}{2}.
