-x-a=3-7
Subtract 7 from both sides.
-x-a=-4
Subtract 7 from 3 to get -4.
-a=-4+x
Add x to both sides.
-a=x-4
The equation is in standard form.
\frac{-a}{-1}=\frac{x-4}{-1}
Divide both sides by -1.
a=\frac{x-4}{-1}
Dividing by -1 undoes the multiplication by -1.
a=4-x
Divide -4+x by -1.
-x-a=3-7
Subtract 7 from both sides.
-x-a=-4
Subtract 7 from 3 to get -4.
-x=-4+a
Add a to both sides.
-x=a-4
The equation is in standard form.
\frac{-x}{-1}=\frac{a-4}{-1}
Divide both sides by -1.
x=\frac{a-4}{-1}
Dividing by -1 undoes the multiplication by -1.
x=4-a
Divide -4+a by -1.
