There are no formulas, use the rules of arithmetic.
\n" ); document.write( "I'll do one and you do the same.
\n" ); document.write( "Move the knowns to one side, unknowns to the other.
\n" ); document.write( "Use additive and multiplicative inverses, distributive and commutative properties
\n" ); document.write( "Add $\"8\"$ to both sides (additive inverse).
\n" ); document.write( " $\"x%2F2-8=7\"$
\n" ); document.write( " $\"x%2F2-8%2B8=7%2B8\"$
\n" ); document.write( " $\"x%2F2%2B0=15\"$
\n" ); document.write( " $\"x%2F2=15\"$
\n" ); document.write( "Multiply both sides by $\"2\"$ (multiplicative inverse)
\n" ); document.write( " $\"2%28x%2F2%29=2%2A15\"$
\n" ); document.write( " $\"%282%2F2%29x=30\"$
\n" ); document.write( " $\"%281%29x=30\"$
\n" ); document.write( " $\"highlight_green%28x=30%29\"$
\n" ); document.write( "Then check your answer in the original equation.
\n" ); document.write( " $\"x%2F2-8=7\"$
\n" ); document.write( " $\"30%2F2-8=7%7D%7D%0D%0A%7B%7B%7B15-8=7\"$
\n" ); document.write( " $\"7=7\"$
\n" ); document.write( "True, right answer.
\n" ); document.write( " \n" ); document.write( "

\n" );
