a=\frac{3}{2}x+\frac{3}{2}a
Use the distributive property to multiply \frac{3}{2} by x+a.
a-\frac{3}{2}a=\frac{3}{2}x
Subtract \frac{3}{2}a from both sides.
-\frac{1}{2}a=\frac{3}{2}x
Combine a and -\frac{3}{2}a to get -\frac{1}{2}a.
-\frac{1}{2}a=\frac{3x}{2}
The equation is in standard form.
\frac{-\frac{1}{2}a}{-\frac{1}{2}}=\frac{3x}{-\frac{1}{2}\times 2}
Multiply both sides by -2.
a=\frac{3x}{-\frac{1}{2}\times 2}
Dividing by -\frac{1}{2} undoes the multiplication by -\frac{1}{2}.
a=-3x
Divide \frac{3x}{2} by -\frac{1}{2} by multiplying \frac{3x}{2} by the reciprocal of -\frac{1}{2}.
a=\frac{3}{2}x+\frac{3}{2}a
Use the distributive property to multiply \frac{3}{2} by x+a.
\frac{3}{2}x+\frac{3}{2}a=a
Swap sides so that all variable terms are on the left hand side.
\frac{3}{2}x=a-\frac{3}{2}a
Subtract \frac{3}{2}a from both sides.
\frac{3}{2}x=-\frac{1}{2}a
Combine a and -\frac{3}{2}a to get -\frac{1}{2}a.
\frac{3}{2}x=-\frac{a}{2}
The equation is in standard form.
\frac{\frac{3}{2}x}{\frac{3}{2}}=-\frac{\frac{a}{2}}{\frac{3}{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{\frac{a}{2}}{\frac{3}{2}}
Dividing by \frac{3}{2} undoes the multiplication by \frac{3}{2}.
x=-\frac{a}{3}
Divide -\frac{a}{2} by \frac{3}{2} by multiplying -\frac{a}{2} by the reciprocal of \frac{3}{2}.
