3x-4x_{3}+93=4x-5+\frac{2}{4}\times 3
Subtract 2 from 2 to get 0.
3x-4x_{3}+93=4x-5+\frac{1}{2}\times 3
Reduce the fraction \frac{2}{4} to lowest terms by extracting and canceling out 2.
3x-4x_{3}+93=4x-5+\frac{3}{2}
Multiply \frac{1}{2} and 3 to get \frac{3}{2}.
3x-4x_{3}+93=4x-\frac{7}{2}
Add -5 and \frac{3}{2} to get -\frac{7}{2}.
3x-4x_{3}+93-4x=-\frac{7}{2}
Subtract 4x from both sides.
-x-4x_{3}+93=-\frac{7}{2}
Combine 3x and -4x to get -x.
-x+93=-\frac{7}{2}+4x_{3}
Add 4x_{3} to both sides.
-x=-\frac{7}{2}+4x_{3}-93
Subtract 93 from both sides.
-x=-\frac{193}{2}+4x_{3}
Subtract 93 from -\frac{7}{2} to get -\frac{193}{2}.
-x=4x_{3}-\frac{193}{2}
The equation is in standard form.
\frac{-x}{-1}=\frac{4x_{3}-\frac{193}{2}}{-1}
Divide both sides by -1.
x=\frac{4x_{3}-\frac{193}{2}}{-1}
Dividing by -1 undoes the multiplication by -1.
x=\frac{193}{2}-4x_{3}
Divide -\frac{193}{2}+4x_{3} by -1.
3x-4x_{3}+93=4x-5+\frac{2}{4}\times 3
Subtract 2 from 2 to get 0.
3x-4x_{3}+93=4x-5+\frac{1}{2}\times 3
Reduce the fraction \frac{2}{4} to lowest terms by extracting and canceling out 2.
3x-4x_{3}+93=4x-5+\frac{3}{2}
Multiply \frac{1}{2} and 3 to get \frac{3}{2}.
3x-4x_{3}+93=4x-\frac{7}{2}
Add -5 and \frac{3}{2} to get -\frac{7}{2}.
-4x_{3}+93=4x-\frac{7}{2}-3x
Subtract 3x from both sides.
-4x_{3}+93=x-\frac{7}{2}
Combine 4x and -3x to get x.
-4x_{3}=x-\frac{7}{2}-93
Subtract 93 from both sides.
-4x_{3}=x-\frac{193}{2}
Subtract 93 from -\frac{7}{2} to get -\frac{193}{2}.
\frac{-4x_{3}}{-4}=\frac{x-\frac{193}{2}}{-4}
Divide both sides by -4.
x_{3}=\frac{x-\frac{193}{2}}{-4}
Dividing by -4 undoes the multiplication by -4.
x_{3}=-\frac{x}{4}+\frac{193}{8}
Divide x-\frac{193}{2} by -4.
