$\"%281%2F3%29%28b-4%29=1\"$
\n" ); document.write( " $\"%281%2F3%29%2Ab-%281%2F3%294=1\"$ Distribute the 1/3
\n" ); document.write( " $\"%281%2F3%29%2Ab%2Bcross%28-4%2F3%2B4%2F3%29=1%2B4%2F3\"$ Add 4/3 to both sides
\n" ); document.write( " $\"%281%2F3%29%2Ab=3%2F3%2B4%2F3\"$ Find common denominator
\n" ); document.write( " $\"%281%2F3%29%2Ab=7%2F3\"$ Add fractions
\n" ); document.write( " $\"cross%28%283%2F1%29%281%2F3%29%29%2Ab=%287%2Fcross%283%29%29%28cross%283%29%2F1%29\"$ Multiply both sides by 3
